Abstract:
AbstractSynthesis, structure and reactions of technetium and rhenium complexes bearing metal-carbon multiple bonds are reported. Addition of LiPh to Cp*M (CO)3 (1a : M = Tc; 1b: M = Re) (Cp* = η5-C5Me5) in Et2O yields the acyl complexes Li[Cp*(CO)2MC(O)Ph]·Et2O (2a: M = Tc; 2 b: M = Re). These are converted with Et3OBF4 into the carbene complexes Cp*(CO)2M = C(OEt)Ph (3a, 3b). Reaction of 3a and 3 b with BCl3 affords the carbyne complexes [Cp*(CO)2M ≡ CPh]BCl4 (4a, 4b) in high yield. The acyl complex 2b can be directly converted into the carbyne complex [Cp*(CO)2Re ≡ CPh]Br (5b), when it is treated with oxalyl bromide. Nucleophiles add at the carbynecarbon atoms of 4a and 4b, as demonstrated by the reaction with NaOCy (Cy = cyclohexyl) to afford the carbene complexes Cp*(CO)2M = C(OCy)Ph (6a, 6b). Similarly, reaction of P(OMe)3 with [Cp*(CO)2Re ≡ CPh]Cl (5b'), the latter being generated in situ from 2b and oxalyl chloride, gives the ylide complex {Cp*(CO)2Re = C[P(OMe)3]Ph}Cl (7b'). In comparison, addition of P(OMe)3 to [Cp*(CO)2Tc ≡ CPh]Cl (5a'), generated in situ from 2a and oxalyl chloride, induces a carbvne-carbonvl coupling reaction resulting in the formation of the ketenyl complex . Thermolysis of the compounds 2a, 2b, 4a, 4b and 7b' has been studied in vacuo and the products of decomposition identified by IR spectroscopy. The solid-state structure of the carbene complexes 3 a and 3 b was determined by single crystal X-ray diffraction studies. Both compounds crystallize in the monoclinic space group P21/n with very similar unit cell data. Striking feature of the isostructural carbene complexes is the nearly perpendicular orientation of the carbene ligand relative to the Cp* ring.

Abstract:
Recent rapid development in homogeneous gold catalysis affords an alternative and particularly thriving strategy for the generation of gold carbenes through gold-catalyzed oxidation/amination/cycloaddition of alkynes, while it avoids the employment of hazardous and potentially explosive diazo compounds as starting materials for carbene generation. In addition to facile and secure operation, gold carbenes generated in this strategy display good chemoselectivity distinct from other metal carbenes produced from the related diazo approach. N-heterocyclic carbene (NHC) gold is a special metal complex that can be used as ancillary ligands, which provides enhanced stability and can also act as an efficient chiral directing group. In this review, we will present an overview of these recent advances in alkyne oxidation/amination/cycloaddition by highlighting their specificity and applicability, aiming to facilitate progress in this very exciting area of research.

Abstract:
Thesis (PhD (Chemistry and Polymer Science))--Stellenbosch University, 2008.
Alkylated acetonitrile that forms during the synthesis of the sulfonium salt, [(Me3)2(MeS)S][BF4], is involved in the formation of new , -unsaturated Fischer-type carbene complexes from (CO)5M=C(OMe)CH2Li (M = Cr, W). Metal migration observed when the substitution product obtained from the reaction of the anionic carbene complexes (CO)5M=C(NMe2)CºC¯ (M = Cr, W) with Ph3PAu+ was left in solution, was also kinetically and theoretically investigated. 1H NMR and quantum mechanical (at the B3LYP level of theory) data indicated a complicated mechanism. The a,b-unsaturated Fischer-type carbene complex, (CO)5Cr=C(OMe)CH=C(Me)NH(Me), obtained from the reaction of (CO)5M=C(OMe)CH2¯ with alkylated acetonitrile, was transformed into the new remote one-N, six-membered, carbene ligand (rN1HC6) complex, (CO)5Cr=C(CH=C(Me)N(Me)CH=C(nBu). The carbene ligand unprecedentedly preferred the softer Rh(CO)2Cl moiety to the Cr(CO)5 metal fragment and transferred readily. A new series of remote and abnormal square planar compounds [r/a(NHC)(PPh3)2MCl]CF3SO3 (M = Pd or Ni) was prepared by oxidative substitution. The various positions for metal-carbon bond formation on a pyridine ring to furnish various ligand types i.e. C2 for nN1HC6, C3 for aN1HC6 or C4 for rN1HC6 received attention. The ligands were arranged in increasing order of carbene character, aNHC < nNHC < rNHC and trans influence, nN2HC5 ~ aN1HC6 ~ nN1HC6 < rN1HC6. In competitive situations, oxidative substitution occurred selectively at C4 of the pyridine ring rather than at C2 and on the aromatic ring containing the heteroatom (C4), rather than on an annealed aromatic ring (C7). Crystal and molecular structure determinations confirmed the preferred coordination sites. Quantum mechanical calculations (at the RI-BP86/SV level of theory) indicated that the chosen carbene ligand has a much larger influence than the metal on the BDE of the M-Ccarbene bond; the farther away the N-atom is from the carbene carbon, the stronger the bond. In complexes that also contain additional external nitrogen atoms, e.g. trans-chloro(N-methyl-1,2,4- trihydro-2-dimethylaminepyrid-4-ylidene)bis(triphenylphosphine)palladium(II) triflate and transchloro( N-methyl-1,2,4-trihydro-2-dimethylaminepyrid-4-ylidene)bis(triphenylphosphine)nickel(II) triflate, stabilisation originates from both the nitrogens. 2-Chloro-1-methyl-1H-pyrid-4-ylidenephenylammonium triflate afforded complexes with both remote as well as normal nitrogen atoms. New azole complexes of palladium and nickel with remote heteroatoms were also prepared from N-methyl-4',4'-dimethyl-2'-thiophen-3-chloro-2-yl-4,5-dihydro-oxazole. Employing the compound 1,5-dichloroanthraquinone, the product of a double oxidative substitution on two Pd centra could be isolated but not alkylated. The fact that the chemical shift of the metal bonded carbon in the 13C NMR spectrum can not be used as absolute measure of carbene character, was emphasised in a compound where the heteroatom was situated seven bonds away from the carbon donor. In efforts to synthesise a sulphur-bridged complex that contains carbene ligands, crystals of transdi- iodobis(1,3-dimethyl-imidazoline-2-ylidene)palladium were obtained. Bridged thiolato complexes with N1HC6 ligands were unexpectedly found in the attempt to substitute the halogen on chosen square planar carbene complexes of palladium, widening the application possibilities of N1HC6 ligands in organometallic chemistry beyond that of catalysis. A trinuclear cluster, [(PdPPh3)3(μ-SMe)3]BF4 was isolated as a by-product of these reactions. A series normal and abnormal thiazolylidene complexes of nickel and palladium were prepared by oxidative substitution of the respective 2-, 4- and 5-bromothiazolium salts with M(PPh3)4 (M = Pd or Ni), and unequivocally characterised. In a preliminary catalytic investigation, all the thiazolinium and simple pyridinium derived palladium complexes showed activity in the Suzuki-Miyaura coupling reaction. Little variation in activity in the order a (N next to carbon donor) > n > a (S next to carbon donor) was found for the former series, whereas decreased activity was exhibited in the sequence r > a > n of the latter group. The pyridinium derived complexes showed superior activity to the thiazolinium ones. The rNHC complex, trans-chloro(N-methyl-1,2,4-trihydro-2- dimethylaminepyrid-4-ylidene)bis(triphenylphosphine)palladium(II) triflate, showed similar Suzuki-Miyaura activity to the standard N2HC5 carbene complex precatalyst, trans-chloro[(1,3- dimethyl-imidazol-2-ylidene)triphenylphosphine]palladium(II) triflate.

Abstract:
With the blend of addressing issues of sustainable energy with the environmental worries regarding emission of greenhouse gases, there is a motivation to target the efficient chemical reduction of CO2. Re(I) integrated photosensitizers and catalysts, synthesized from commercially available ligands, are introduced with the selective CO2 reduction of formic acid, making for a unique class of Re(I) catalysts typically selective for CO as a reduction product. Furthermore, synthesized Zn(II) phosphino aminopyridine complexes are structurally and computationally characterized as well as observed to function as unprecedented electrocatalysts for the reduction of CO2 to formic acid and CO. Lastly, with the importance and popularity of N-heterocyclic carbenes (NHCs) as a class of ligands in the field of organometallic catalysis, six-membered perimidine based carbenes are further explored. Synthesis of a chelating pyridyl-perimidine NHC in addition to potential transition metal catalysts are also attempted.

Prof. Dr. Metin Zora August 2005, 80 pages Construction of highly functionalized five-membered rings via cycloaddition reaction of cyclopropylcarbene-chromium complex with alkynes has become a very active area of research in recent years by virtue of their presence in antitumour natural products. Also with the finding that ferrocene derivatives are active against various tumours, considerable interest has been devoted to the synthesis of new ferrocene derivatives since properly functionalized ferrocene derivatives could be potential antitumour substances. So, the incorporation of the essential structural features of cyclopentenones with a ferrocene moiety could provide compounds with enhanced antitumour activities. For this purpose, we have investigated the reaction between cyclopropylcarbene-chromium complex and ferrocenyl alkynes. The reaction of cyclopropylcarbene-chromium complex with ferrocenyl alkynes afforded &

The reaction was regioselective both with terminal ferrocenyl alkynes and internal unsymmetrical ferrocenyl alkynes.

Abstract:
The work described herein focuses on the synthesis and characterisation of copper(I) complexes bearing N-heterocyclic carbene (NHC) ligands, their use in catalysis as well as organometallic synthesis and related reaction mechanisms. Two classes of complexes were considered: neutral NHC-Cu(I) species and their cationic analogues. Concerning the former, initial efforts were focused on the development of a general and straightforward synthetic methodology towards complexes of the type [Cu(X)(NHC)] (X = Cl, Br, I). More than 10 NHC-Cu(I) species were synthesised in high yields under mild conditions, in air and using technical grade solvents. These complexes exhibited interesting activity in the catalytic dehydrogenation of formic acid/amine adducts proving in three times more efficiency than the copper salts previously employed in such a reaction. Hydroxide- and tert-butoxide analogues showed to be efficient catalysts in the N-methylation of amines with CO₂ as carbon source, and in the dehydrogenative coupling of silanes and carboxylic acids. Experimental and computational work were carried out in order to elucidate the mechanism of these transformations. Regarding the use of these species in organometallic synthesis, homo- and heteroleptic bis-NHC-Cu(I) complexes were employed as carbene transfer reagents to other transition metals. Aside from well-known cationic gold(I) species, two novel palladium(II) analogues were isolated and fully characterised.

z, Canet M.S., Department of Chemistry Supervisor: Assoc. Prof. Dr. Metin Zora August 2005, 85 pages Synthesis of seven-membered ring systems such as cycloheptadienones has attracted a great deal of attention in organic chemistry since they are present in a variety of biologically important molecules. Incorporation of the essential structures of such compounds with a ferrocene moiety instead of an aryl group could provide subtances with enhanced antitumor activities since some ferrocene derivatives have already proved to be active against a number of tumors. To develop a ferrocenyl-substituted seven-membered ring forming reaction, we have investigated the reaction of cyclopropylcarbene-molybdenum complex with ferrocenyl-substituted alkynes.

The reaction between cyclopropylcarbene-molybdenum complex and ferrocenyl alkynes produced ferrocenyl-substituted cycloheptadienones 26, hydrolysis product of cycloheptadienones, 27, &

Terminal alkynes, trimethyl- and formyl-substituted alkynes did not produce any expected product, possibly depending on the steric and electronic effects, and/or the polymerization of the alkyne. Proposed mechanism for the formation of cycloheptadienones involves metallacyclobutene formation, electrocyclic ring opening, electrocyclic ring closure, CO insertion, reductive elimination.

Ce travail de recherche est consacré au développement de catalyseurs à base de métaux de transition abondants de la première rangée du tableau périodique, tels que Mn, Fe, et Ni, pour les réactions d'hydro-élémentation. Tout d'abord, l'hydrosilylation de cétones et d'aldéhydes a été accomplie en utilisant un système catalytique simple Ni(OAc)₂ 4H2O/PCy₃ avec le PMHS, silane peu coûteux et stable en tant que source d'hydrure. L'amination réductrice d'aldéhydes avec des amines a également été réalisée avec le même système catalytique et le TMDS, comme silane. Deuxièmement, l’efficacité des complexes de manganèse demi-sandwich CpMn(CO)₂(IMes) a été prouvée pour la réduction des aldéhydes et des cétones en présence de Ph₂SiH₂ (1,5 équiv.) sous irradiation UV. La transformation difficile d'acides carboxyliques en aldéhydes a été effectuée à l'aide de Mn₂(CO)₁₀ et de Et3SiH. Troisièmement, la méthylation des amines secondaires avec le carbonate de diméthyle en tant que source C1 a été démontrée dans des conditions catalytique douces avec [CpFe(CO)₂(IMes)]I. Ensuite, l'hydroboration d'alcènes et d'alcynes fonctionnalisés a été réalisée en présence d’un complexe de fer (0), Fe(CO)₄(IMes) sous irradiation UV. Enfin, la réaction d'hydroboration a été étendue avec succès à la réduction de CO₂ en methoxyboranes avec Fe(CO)₃[P(OPh)₃]₂ en tant que catalyseur et les diverses sources de borane, tels que HBpin, HBcat ou 9-BBN
This research work deals with the use of the catalysts based on the earth-abundant transition metals of the first row of the periodic table, such as Mn, Fe, and Ni, for hydroelementation reactions. First of all, the hydrosilylation of aldehydes and ketones was accomplished using a simple Ni(OAc)₂ 4H₂O/PCy₃ catalytic system with the inexpensive and stable silane PMHS as the hydride source. The reductive amination of aldehydes with amines was also achieved with the same catalytic system and TMDS, as the silane. Second, the efficiency of manganese half-sandwich complex CpMn(CO)₂(IMes) was exemplified for the reduction of aldehydes and ketones in the presence of Ph ₂ SiH ₂ (1.5 equiv.) under UV irradiation at room temperature. Still with manganese, the challenging transformation of carboxylic acids to aldehydes was performed using commercial Mn₂ (CO)₁₀ and Et₃SiH. Third, the methylation of the secondary amines with dimethyl carbonate as an alternative and safe C1 source was demonstrated under mild conditions with [CpFe(CO)₂(IMes)]I as the catalyst. Then, the hydroboration of functionalized alkenes and alkynes was catalyzed by an iron(0) carbonyl complex Fe(CO)₄(IMes) under UV irradiation. Finally, the hydroboration reaction was successfully extended to the reduction of CO₂ to methoxyboranes with Fe(CO)₃[P(OPh)₃]₂ as the catalyst and the borane sources, such as HBpin, HBcat or 9-BBN

Abstract:
This thesis is comprised of two parts. The first part describes the synthesis of cyclopentadienyltungsten complexes containing a pendant alkyne group (I), and the subsequent photo-induced intramolecular coordination of the alkyne, forming complexes such as II. Compounds containing intramolecularly coordinated alkynes are rare, and this is the first example using cyclopentadiene as the core ligand. The second part describes the synthesis and structural characterisation of a number of novel metal complexes containing N-heterocyclic carbene ligands, some containing particular functionality for taylored applications. New methods were used to form complexes of rhodium, iridium, silver and gold (eg. III, IV). Structural and spectroscopic properties of the complexes were correlated with electronic characteristics of the ancillary ligands. A number of rhodium and iridium complexes (eg. IV) derived from imidazolium-linked cyclophanes were synthesised and structurally characterised. Complexes of N-heterocyclic carbenes with pendant ionic groups were synthesised, and a preliminary examination of their catalytic activity in water was performed. N-Heterocyclic carbenes complexes containing an electron withdrawing nitro group were synthesised and the effect of the nitro group on metal-ligand bonding was examined.

Abstract:
Coal, due to its heterogenous nature and complex structure; physical, chemical and petrographic, introduces two-fold complications during its combustion in power generation. Organic and inorganic constituents in various petrographic states alter chemically and physically. The products of coal combustion; unburned carbon, deposits, oxides of metals and non-metals, metal and non-metal complexes, need to be identified qualitatively and quantitatively to increase the coal combustion efficiency and to optimize the durability of power plant components. This paper will describe the usage of various analytical tools like NMR, ESR, IR, Electron Microscopy, X-Ray, Fluorescent Microscopy coupled with Wet Analysis to analyze coal and its derivatives. Each spectroscopy will be related to a specific aspect of coal and its derivatives. The limiting conditions and the range of application of each of the tools will be provided. The knowledge of these ranges will help in monitoring accurate emission levels of a particulate concentration, NOx, SOx and will control several phenomena such as deposition, corrosion and erosion.

Abstract:
Abstract This paper presents a complex approach to designing ceramic blades dovetail joints. Two ceramic materials were considered: diamond reinforced silicon carbide and hot pressed silicon nitride (only in contact testing). The model blades were made from diamond reinforced silicon carbide due to its availability and mature technology. Part 1 describes the models of mechanical and thermal contact and contains experimental data on contact strength and thermal contact conductance. Part 2 investigates the effect of stress concentration and scale factor on the fracture of ceramic test pieces. Part 3 proposes a theoretical-experimental method to estimate friction coefficient in a dovetail joint. We also investigated the character of the ceramic blades fracture during the rotor spin-up. Part 4 deals with automating the design process of the ceramic blades dovetail joints using experimental data.

Abstract:
Abstract Additive friction stir deposition is an emerging solid-state additive manufacturing technology that has shown promise for bulk fabrication of metals and metal-matrix composites. Here, we perform a preliminary investigation into the influence of tool geometries on the particle distribution and matrix-particle coherence of SiC in the matrix of Aluminum Alloy 6061 and commercially pure Copper. Two tool geometries have been used: (1) a simple, featureless tool and (2) a complex geometry tool with four surface protrusions. For the simple tool geometry, the Al-SiC is observed to have less uniform bulk distribution of the reinforcement phase, resulting in regions of highly concentrated SiC reinforcement (up to 69 area%). The Cu-SiC sample produced with the simple geometry tool has a homogeneous distribution. The samples produced with the complex geometry tool show more uniform distribution of SiC reinforcement throughout the bulk of the deposit with local reinforcement concentrations reaching up to 42 area% and 28 area% for the Al and Cu matrix, respectively. All tool geometries create samples with good interfaces that have continuous contact between the particle and matrix phases, even including particles with sharp angles and non-spherical surfaces. Further optimization of tool geometries and processing conditions can lead to improved control of the reinforcement phase distribution and enable design of metal-matrix composites with tailored site-specific properties.

Full text
Abstract:
The rheological behavior of various complex fluids was explored in this experimental study. Nanofluids were obtained by mixing nanoparticles with various solvents. The solvents consisted of metal salt eutectics that melt at high temperatures (exceeding 200 °C) depending on the composition of the metal salts in the eutectics. The rheological behaviors of these high temperature solvents were measured as a function of temperature before and after mixing with different types of nanoparticles (chemical composition, size, shape and concentration). These nanofluids exhibited non-Newtonian behavior (shear thinning behavior) while some of the other nanofluids were surprisingly found to have Newtonian behavior. It was observed that high aspect ratio nanoparticles (e.g., stick shaped carbon nanotubes) were more likely to cause shear thinning behavior of the resulting nanofluids.

Full text
Abstract:
Currently, J-estimation scheme procedures to predict the load-carrying capacity of idealized circumferential through-wall cracks in nuclear grade piping materials employ analytical or numerical procedures coupled with the fracture toughness of the material to predict the pipe response. However, with the advent of primary water stress corrosion cracking (PWSCC), complex-shaped cracks occur in dissimilar metal (DM) welds. These welds consist of a nickel-based weld joining stainless steel and carbon steel base metals. The NRC Office of Nuclear Regulatory Research (RES) is conducting a program to investigate the behavior of circumferential through-wall and complex cracks in DM welds. In a prior paper, a series of full-scale pipe bend and laboratory-sized fracture experiments were documented. Initial analyses of those test results suggest that reasonable prediction of through-wall crack response is obtained from typical J-estimation scheme procedures using the weld toughness from a compact tension (CT) specimen and the appropriate material strength. In addition, the J-R curves from the through-wall cracked pipe tests, calculated using published η-factor solutions and numerical techniques, were very similar to the CT J-R curves. In this paper, the fracture toughness for the circumferential complex cracked experiments, which was developed from a modified η-factor solution, is presented. These results are compared to the CT and through-wall crack pipe J-R curve results. In addition, predictions of load carrying capacity using the complex crack J-R curve and through-wall crack J-estimation schemes are presented and illustrate the need for the development of a complex crack J-estimation scheme. To support this development, a net-section collapse solution and a modified K-solution is presented. Finally, the need for additional work to generalize the elastic solution and its incorporation into a closed-form J-estimation scheme is discussed.

Abstract:
Fiber reinforced polymers are widely used in the transportation, aerospace and chemical industries. In rare instances these materials are produced net-shape, and secondary processing such as machining and assembly may be required to produce a finished product. Because fiber reinforced polymers are heterogeneous materials, they do not machine in a similar way to metals. Thus, the theory of metal machining is not valid for the analysis of machining of fiber reinforced composites. Previous attempts in modeling this problem have adopted Merchant’s theory for metal cutting by assuming that chip formation takes place in a shear plane where the inclination angle is determined by the minimum energy principle. This class of models showed that model predictions are valid only for fiber orientations less than 60°. Furthermore, these models are incapable of predicting cutting forces for multidirectional laminates or complex tool geometry. The work presented here focuses on providing a predictive model for the cutting forces in milling both unidirectional and multidirectional laminates. The model is based on the specific cutting energy principle and accounts for a wide range of fiber orientations and chip thickness. Results from this model were found to be in good agreement with experimental results over the entire range of fiber orientations from 0 to 180°.
