Abstract:

Rotationally resolved infrared absorption spectra of jet-cooled transition metal carbonyls in the region of CO stretching vibrations near 2000 cm-1 are reported in this thesis. The molecules span spherical, symmetric and asymmetric tops. Theories and their deductions related to the explanation of the various aspects of spectra are simply elucidated. The measurement of the band centres of spectra of M(CO)6 (M=Cr, Mo, W) has an improvement of 103 in precision. The rotational constants determined are very close to those derived from electron diffraction results. Analysis of the spectra of MeMn(CO)5 (Me=CH3, CD3) of two strongly allowed bands yielded values for the band centres and rotational constants for parallel bands of both isotopic species, and for the perpendicular band of CH3Mn(CO)5; the latter also provided an estimate of the Coriolis constant for this vibration. The spectra were consistent with essentially free rotation of the methyl group. The rotational constants were in close agreement with those derived from electron diffraction data; however, the B rotation constants provide a revised estimate for the axial Mn-CO bond length. The parallel band of C5H5Mn(CO)3 is analysed and the band centre and B rotational constant of excited state are estimated. Three bands of C4H6Fe(C0)3, one of which exhibits essentially a-type transitions, the second b-type transitions, and the third a- and c-type transitions, are analysed. The results confirm the effective Cs symmetry of the Fe(C0)3 unit and yield values for the band centres and rotational constants of the upper levels of two of the three bands. The relative intensities of the a and c components of the hybrid band provide an estimate of 1:4 for the ratio of the square of the transition moments of this vibration. Spectra of C5H5Co(CO)2 are also reported, and band centres of the two bands of CO stretching vibrations are estimated.

Abstract:

Many organometallic reactions are solvent-dependent, suggesting solvent molecules interact with reaction intermediates. Studies of the solvent exchange reaction of group 6 transition metal carbonyls with moderately binding ligands have provided insight into these interactions, however, studies of the mechanism for this reaction with weakly binding ligands have not been performed. Experiments were conducted on the nanosecond time scale in methylcyclohexane over the temperature range of 4 to 44 °C using Step Scan FTIR (SS FTIR) spectroscopy with weakly binding ligands benzene and mesitylene. Upon photolysis of the metal hexacarbonyls, the kinetically favored product (M(CO)5(solv)), decays following pseudo-first-order kinetics to the thermodynamical favored product, M(CO)5(L). The decay is fit using a single exponential decay with a single exponential instrument response function, time zero and an offset. An Arrhenius plot yielded activation energies of 23.7 kJ/mol (M = Mo, L = benzene), 35.1 kJ/mol (M = W, L = benzene) and 29.8 kJ/mol (M = Mo, L = mesitylene). DFT calculations using NWCHEM gave binding energies of 45.8 and 54.3 kJ mol-1 for Mo(CO)5C6H12 and W(CO)5C6H12. The experimental and computational results suggest the exchange mechanism proceeds through an associative pathway, were slightly negative values of the entropy of reaction denote that the transition state has greater metal solvent bond breaking character then the more moderately binding ligands in the literature. Density Functional theory was used to calculate C-O vibrational frequencies of metal carbonyl complexes measured in our work and other complexes from the literature, with density functionals B3LYP, M06 and M06-L. Measured and computational frequencies were compared to obtain both an overall vibrational shift and a scaling factor. Scaling factors were found to be 0.9519±0.0095 for B3LYP, 0.9429 ± 0.0087 for M06 and 0.9565 ± 0.0095 for M06-L with overall shifts of 102 ± 16, 121 ± 15, 93 ± 17 cm-1, respectively. The molybdenum mediated Pauson-Khand reaction, a [2+2+1] cyclo-addition begins very similarly to the solvent exchange reaction on molybdenum. The initial product, the solvated complex, decays away with pseudo-first-order kinetics as the solvent is replaced by the C-C triple bond in 2-(2-propen-1-yl)-2-(2-propyn-1-yl)-,1,3-diethyl ester. An Arrhenius plot over the temperature range of -8 to 20° C yielded an energy of activation of 15.6 kJ/mol.

Abstract:

The collision-induced dissociation (CID) of transition metal carbonyl clusters have been recorded and presented using the recently developed technique of energy-dependent electrospray ionisation mass spectrometry (EDESI). EDESI has been improved to incorporate breakdown graphs, allowing complete fragmentation data to be presented. EDESI spectra facilitate the assignment of all ligands, and assist in determining the composition of the cluster core. Electron autodetachment was observed upon ligand loss from multiply charged clusters. For certain clusters, a remarkable amount of structural information was extracted. For example, the structure of [{PtRu₅C(CO)₁₅}₂Pt(CO)₂]^2- was correctly predicted from the EDESI spectrum. Photoelectron spectroscopy was carried out on three clusters and selected CID products in the gas phase. The photoelectron spectra for each species revealed a high density of electronic states, and a reduction in electron binding energy was observed on removal of CO ligands. For the dianionic clusters, electron binding energy was approximately zero where electron autodetachment was observed in the EDESI spectra. The gas-phase reactivity of a naked metal cluster has been studied with the use of a Fourier transform ion cyclotron resonance mass spectrometer. A novel “top down” approach has been used to form [CoRu₃]^- in the gas phase, by synthesising [PPN][CoRu₃(CO)₁₃] in the condensed phase and using CID in the electrospray ionisation source to strip the cluster of its ligands. The top down approach to gas phase clusters removes the requirement for a custom-built cluster source, and will allow the study of otherwise difficult to produce mixed-metal systems will interstitial ligands. The reactivity of [CoRu₃]^- with CH₄ and H₂ has been studied, and with use of tandem mass spectrometry, [CoRuC]^- (a product of the reaction between [CoRu₃]^- and CH₄) was isolated and further reacted with CH₄.

Abstract:

Stable, readily available, transition metal cluster carbonyl compounds, such as Os₃(CO)₁₂, Ir₄(CO)₁₂, Rh₆(CO)₁₆, have been shown to easily aggregate into multi-nuclear supraclusters following exposure to pulsed ultraviolet laser radiation (laser desorption ionisation, LDI) in the source region of a mass spectrometer. The aggregation process has been studied from the resulting mass spectra, using both of time-of-flight mass spectrometry (TOF MS) and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). Larger cluster precursors tend to aggregate via the stepwise addition of whole metal cores, whereas the smaller tri-nuclear osmium cluster can produce supraclusters with variable numbers of metal atoms present. Interestingly, laser desorption/ionisation of Os₃(CO)₁₂ leads to the formation of prominent dodecaosmium cluster negative ions, such as [Os₁₂(CO)₂₃]^-. As far as we are aware, no homoleptic dodecaosmium carbonyl species has been prepared via traditional synthetic methods, highlighting the future potential of this approach if techniques for stabilising these complexes and isolating them can be developed. The LDI spectra also exhibit prominent metastable decay products, corresponding to evaporative carbonyl ligand loss, a phenomenon known as post-source decay. The rates of metastable decay have then been determined for the mono-isotopic rhodium supraclusters. In addition the transition metal carbonyl precursors used in the aggregation experiments have been studied by electrospray ionisation using quadrupole and Fourier transform ion cyclotron resonance mass spectrometers. In this case clusters require derivatisation with an alkoxide agent to produce a carbomethoxy ligand ([COOCH₃]^-) on the cluster, providing them with the necessary charge for mass spectrometric detection. The recently introduced technique of Energy Dependent Electrospray Ionisation mass spectrometry (EDESI-MS) has been used to investigate the relative strengths of the metal-to-carbonyl bonds using a process known as in-source collision-induced dissociation. From this data bond dissociation energies for the sequential removal of carbonyl ligands from the transition metal cluster precursor have been determined. FT-ICR MS experiments confirm the presence of a second decay channel leading to the formation of metal carbonyl hydride species, produced from the activation of the carbomethoxy ligand. Preliminary studies of these coordinatively unsaturated transition metal carbonyls with hydrocarbons have also been carried out.

Abstract:

This thesis is concerned with the electronic absorption spectroscopy and photochemical relaxation mechanisms of binary metal carbonyl complexes. These paradigm complexes exhibit a wide range of photoinduced vibronic coupling related phenomena that are only recently beginning to be understood with the development of modern experimental and computational techniques. These experiments have shown that after irradiation using ultrafast (femtosecond) laser pulses an unsaturated photoproduct is produced, and possibly relaxes through a conical intersection at a Jahn-Teller active geometry, on the same ultrafast timescale. However while experiment can imply the presence of conical intersection, only theoretical methods can confirm this and accurately probe the appropriate part of the potential energy surfaces relevant to this mechanism. The accurate assignment of the electronic excited states of these carbonyls is also a matter of debate with different theoretical and experimental techniques applied to these systems over the years. The large density of excited states of different character within a small energy range and the high computational expense of studying transition metal complexes with highly correlated methods presents a considerable challenge to the theoretical chemist. The research presented in this thesis falls into two main parts, firstly the electronic excited states of the binary transition metal carbonyl complexes Fe(CO)5, Cr(CO)6 and Ni(CO)4 were studied with highly correlated coupled cluster methods as well as their one-photon and two-photon absorption spectra. These results were compared with previous experimental and theoretical results. The electronic excited states and one-photon absorption spectra were also studied for the group 7 mixed-metal bimetallic carbonyls (MnTc(CO)10, MnRe(CO)10 and TcRe(CO)10) for the first time with time-dependent density functional theory (TD-DFT), the ability of TD-DFT methods to describe charge-transfer states was also investigated here. The second part of this thesis focussed on the relaxation pathways of the 2Mn(CO)5 and 1Fe(CO)4 initial photoproducts of the photodissociation of Mn2(CO)10 and Fe(CO)5 respectively using CASSCF. Both were found to relax to their lowest energy state through a Jahn-Teller induced conical intersection at a Jahn-Teller active geometry in agreement with experimental observation.

Abstract:

A detailed mechanistic investigation of the previously reported ruthenium pseudo-dipeptide-catalyzed asymmetric transfer hydrogenation (ATH) of aromatic ketones was performed. It was found that the addition of alkali metals has a large influence on both the reaction rate and the selectivity, and that the rate of the reaction was substantially increased when THF was used as a co-solvent. A novel bimetallic mechanism for the ruthenium pseudo-dipeptide-catalyzed asymmetric reduction of prochiral ketones was proposed. There is a demand for a larger substrate scope in the ATH reaction, and heteroaromatic ketones are traditionally more challenging substrates. Normally a catalyst is developed for one benchmark substrate, and a substrate screen is carried out with the best performing catalyst. There is a high probability that for different substrates, another catalyst could outperform the one used. To circumvent this issue, a multiple screen was executed, employing a variety of ligands from different families within our group’s ligand library, and different heteroaromatic ketones to fine-tune and to find the optimum catalyst depending on the substrate. The acquired information was used in the formal total syntheses of (R)-fluoxetine and (S)-duloxetine, where the key reduction step was performed with high enantioselectivities and high yield, in each case. Furthermore, a new iron-N-heterocyclic carbene (NHC)-catalyzed hydrosilylation (HS) protocol was developed. An active catalyst was formed in situ from readily available imidazolium salts together with an iron source, and the inexpensive and benign polymethylhydrosiloxane (PMHS) was used as hydride donor. A set of sterically less demanding, potentially bidentate NHC precursors was prepared. The effect proved to be remarkable, and an unprecedented activity was observed when combining them with iron. The same system was also explored in the reduction of amides to amines with satisfactory results.

At the time of doctoral defense, the following paper was unpublished and had a status as follows: Paper 2: Manuscript.
