Abstract:
The copper(II) acetate mediated oxidative homocoupling of terminal alkynes, namely, the Eglinton coupling, has been studied with DFT methods. The mechanism of the whole reaction has been modeled using phenylacetylene as substrate. The obtained results indicate that, in contrast to some classical proposals, the reaction does not involve the formation of free alkynyl radicals and proceeds by the dimerization of copper(II) alkynyl complexes followed by a bimetallic reductive elimination. The calculations demonstrate that the rate limiting-step of the reaction is the alkyne deprotonation and that more acidic substrates provide faster reactions, in agreement with the experimental observations.

Abstract:
Non-linear optical (NLO) materials are able to modify the propagation characteristics of light. Such materials have a range of potential applications in advanced technologies and are therefore of considerable interest. This account summarizes the development of one class of organometallics as potential NLO materials, namely ruthenium alkynyl complexes. These are available in high yields by straightforward synthetic procedures and have good thermal and environmental stability. In studies ranging from small molecules (molecular weights ~1000) to second-generation dendrimers (with molecular weights of more than 20000), the author’s group and collaborators have assayed the NLO effects in complexes with a variety of ‘multipolar’ charge distributions (dipolar, quadrupolar, octupolar), revealing that ruthenium alkynyl complexes can be engineered to display record and near-record values of the parameters responsible for various interesting NLO effects. In particular, recent studies driven by the current focus on optimizing molecular multiphoton absorption cross-sections have afforded several examples with world-record values of these key coefficients. The author’s group has also shown that the fully reversible redox processes undergone by many ruthenium alkynyl complexes are a distinctive feature that can be exploited to afford molecular NLO switches, because the different and reversibly accessible redox forms of the complexes exhibit measurably different NLO responses. This unique type of switching has been extended in two ways to afford molecular switches with multiple accessible NLO states. First, ruthenium alkynyl complexes have been subjected to various ‘orthogonal’ (independent) switching stimuli (specifically oxidation–reduction, protonation–deprotonation, and photoisomerization), affording complexes that function as NLO switches with up to six distinct NLO states. Second, heterobimetallic complexes coupling ruthenium alkynyl and iron alkynyl centres have been prepared that exhibit multiple redox-accessible NLO states.

Abstract:
Reaction of bis(cycloocta-1,5-diene)platinum(0) with the (alkynyl)phenylsilanes Ph3SiC2But, Ph2Si(C2But)2 and PhSi(C2But)3 gives, respectively, [Pt (Ph3SiC2But)2] (1b), [Pt {Ph2Si(C2But)}]2 (2b), and [Pt {PhSi(C2But)3}]2 (4b), which contain zerovalent platinum atoms coordinated by two alkyne units. Spectroscopic data indicate that (2b) and (4b) contain two PtC4 and two SiC4 tetrahedra joined at the corners. X-Ray crystallography shows that complex (4b) is isostructural and isomorphous with the known nickel analogue, two of the alkyne units being uncoordinated; the central eight-membered ring comprising two silicon, four alkyne carbon and two platinum atoms has an approximate chair conformation. In contrast, the monomer (1b) is isostructural but not isomorphous with the analogous nickel compound (1a); in the crystal there is evidence for a weak intramolecular phenyl-phenyl interaction.

Abstract:
This Thesis describes the synthesis and characterisation of a series of trans-bis(alkynyl) ruthenium complexes, trans-[Ru(C≡CR)2(L)4], to better understand how the variation of the metal ancillary ligands (L) affect electronic structure and spectroscopic properties, chemical reactivity, and behaviour in metal|molecule|metal junctions. Reactions of cis-[RuCl2(dppm)2] with terminal alkyne HC≡CC6H4-4-R, in the presence of TlBF4 and base, gives into trans-bis(alkynyl) complexes, trans-[Ru(C≡CC6H4-4-R)2(dppm)2], for electron withdrawing R groups or cationic η3-butenynyl complexes, E-­[Ru(η3-{HC(C6H4-4-R)=CC≡C(C6H4-4-R)})(dppm)2]+ for electron donating R groups. Reactions of cis-[RuCl2(dppm)2] with di-terminal alkynes HC≡CC6H4-2,5-X2-4-C≡CH, in the presence of TlBF4 and [NnBu4]Cl, gives trans-[RuCl(C≡CC6H2-2,5-X2-4-CCl=CH2)(dppm)2], inferring a quinoidal cumulene intermediate. Multi-metallic trans-bis(alkynyl) {Ru(dppe)2} complexes, varying in binding groups and bridging ligands, have been prepared. Reversible oxidation processes, whilst corresponding to the number of integrated metal centres, exhibit a high degree of alkynyl character in all cases. The vibrational and electronic spectra of both neutral and oxidised complexes are complicated by the presence of numerous spectroscopically distinct rotamer conformations and redox isomers. For example in the case of mono-oxidised complexes, a principal low-energy (π-π*) NIR band is exhibited along with multiple higher energy (MLCT-type) NIR bands, which can be assigned by comparison with smaller model systems. Finally, trans-bis(alkynyl) {Ru{P(OEt)3}4} complexes have been synthesised. As a result of the increased (pseudo D4h) molecular symmetry and consequent fewer distinct rotamer conformations, a lesser number of NIR bands are exhibited for trans­[Ru(C≡CR)2{P(OEt)3}4]+ than bis-chelating dppm and dppe derivatives. Between trans-[Ru(C≡CR)2(PPʹ)] (PPʹ = (dppe)2, {P(OEt)3}4) complexes, the {Ru(dppe)2} derivatives give rise to conductance histograms with additional features. These features are attributed to contacts formed at or across the dppe-phenyl rings, leading to suggestions that phosphite complexes might be novel ‘insulated’ molecular wires.

Abstract:
[Truncated abstract] This thesis describes various synthetic approaches toward the synthesis of highly conjugated complexes incorporating multiple transition metal centres. Particular attention is given to the synthesis of mononuclear complexes that allow for the facile assembly of discrete oligo- and poly-nuclear complexes in a controlled, stepwise fashion. Conjugated multi-metallic materials are of interest on account of their unique photophysical and electronic properties, with a particular emphasis on elucidating the nature of intramolecular communication between multiple metal centres. Chapter 1 provides a survey of these topics and current research efforts in the field. Chapter 2 describes the synthesis of Group-VIII allenylidene complexes incorporating a terminal bipyridyl moiety that provides a site for further coordination. The new compound 9-hydroxy-9-ethynyl-4,5-diazafluorene was synthesised, and reaction of this proligand with a coordinatively unsaturated metal fragment yields the allenylidene complexes [MCl(PnP)2=C=C=(4,5-diazafluoren-9-yl)]PF6 (M = Ru, PnP = dppm, dppe, dmpe; M = Os, PnP = dppm) and [CpRu(dppe)=C=C=(4,5-diazafluoren- 9-yl)]PF6. The dmpe-ligated complex is particularly susceptible to decomposition, though it was possible to obtain partial spectroscopic characterisation in addition to a single-crystal X-ray structural determination. The remaining allenylidene complexes are stable compounds readily characterised by standard spectroscopic and electrochemical means, with the bis(diphosphine) complexes characterised by single crystal X-ray structural determinations. ... Reactions of the proligand with [RuCl(PnP)2]+ (PnP = dppm, dppe) led to the isolation of a product spectroscopically consistent with the formation of the target cationic allenylidene complexes, though the complexes were not readily purified and the identity of the accompanying anion was not elucidated. The new compound 4-hydroxy-4- ethynyl-cyclopentadithiophene was also prepared, though the compound was found to be highly unstable and susceptible to rapid decomposition. The derived allenylidene complexes [RuCl(PnP)2=C=C=(4-cyclopentadithiophene)]PF6 (PnP = dppm, dppe) were isolated in a pure form and the complexes stable toward spontaneous decomposition. The thienyl-derived allenylidene complexes were characterised by spectroscopic and electrochemical techniques, with a single-crystal X-ray structural determination undertaken for [RuCl(dppm)2=C=C=(4-cyclopentaditiophene)]PF6. Electrochemical properties are significantly different between the complexes, and also show significant variation between electrodes and solvents. The terminal thienyl substituents are electroactive and show one or two oxidation processes consistent with oligomerisation of the thienyl moiety in dichloromethane solvent, and in acetonitrile solvent cyclic voltammograms are consistent with the deposition of an electroactive film on the electrode surface. The electro-polymerisation of the thienylallenylidene complexes offers a promising new route toward multi-metallic allenylidene complexes.

Abstract:
The main protease SARS-CoV-2 3CL Mpro (3CL-Mpro) is an attractive target for developing antiviral inhibitors due to its essential role in processing the polyproteins translated from viral coronavirus RNA. In this work, it was obtained non-covalent complexes of this protease with two distinct ligands, a peptidyl Michael acceptor (N3) and a ketone-based compound (V2M). The complexes were modeled from processed crystallographic data (PDB id: 6LU7 and 6XHM respectively) using combined quantum mechanics/molecular mechanics (QM/MM) calculations. The QM region was treated at the PBE-def2-SV(P) level, while the Amber-ff19SB force field was used to describe the MM region. The obtained models were used to perform calculations for describing the protease/ligand binding, based in the framework of the Density Functional Theory (DFT) and within the Molecular Fractionation with Conjugated Caps (MFCC) scheme. Our results have shown values for the total interaction energies of -111.84 and -111.64 kcal mol-1 having as ligands a N3 and V2M, respectively. Most importantly, it was possible to assess the relative individual amino acid energy contribution for the binding of both ligands considering residues around them up to 10 Å of radial distance. Residues Gln189, Met165, Glu166, His164, and Asn142 were identified as main interacting amino acid residues for both complexes, being their negative interaction energy contributions higher than -5.0 kcal mol-1. In the case of 3CL-Mpro/ V2M complex, we should add His41, Ser144, and Cys145 as main contributing residues. Our data also have shown that interactions of type π-amide, π-alkyl and alkyl-alkyl and carbon hydrogen bonds should be also considered in order to explain the binding of 3CL-Mpro with the selected inhibitors. Our results also determined that the carbonyl-L-leucinamide scaffold of both inhibitors is its main determinant of binding with a contribution to the energy of interaction of 54.51 and 50.69 kcal mol-1 for N3 and V2M, respectively.

Abstract:
The paper present the results carried out in order to produce synthetic ester oils with a complex structure on the basis of sebacic acid with beneficial tribological properties. Three series of unsymmetrical diesters have been synthesized by taking into account superior aliphatic alcohols such as 2-ethyl-hexanol, isodecanol and isotridecanol along with special alcohols of a complex alkyl-aryl structure, namely 2-phenoxy-ethanol, 2-[(o sec butyl)-phenoxy] ethanol and 2-[(p-nonyl)-phenoxy] ethanol, respectively. There were also synthesized the symmetrical (homogeneous) esters based on these special aliphatic-aromatic alcohols.

Abstract:
As a useful flotation agent, the xanthate ligand, O-alkyldithiocarbonates, has been used by different countries by its easy and inexpensive synthesis. More recently papers explored many different applications using this ligand within a complex of several metals cation. In order to study the proprieties of the lead (II) complex with such ligand, the object of this work is to provide a better understanding of the Pb-S bond using different theoretical approaches as NBO, EDA and QTAIM analysis and the influence caused by the different alkyl groups of the ligand. By an optimized structure, the NBO showed that the Pb-S is mainly composed by p orbital of the lead and by the p lone pair of the sulfur atom. The calculation with different alkyl groups highlights that the presence of a larger hydrocarbon chain provides a higher contribution of the s orbital of the lead atom to the interaction. Through the EDA analysis, the interaction between ligand and metal has the predominance of an electrostatic character. The size of the alkyl group has an impact on the value of both covalent and electrostatic character, making the interaction more covalent, due to a higher presence of an electronic density on sulfur atom. This density can be evaluated by the topological study of the QTAIM analysis, which enhances the fact that the charge over the sulfur atom gets higher when using a larger alkyl group for the xanthate ligand.
