Abstract:

Transition-metal chemistry in ionic liquids (IL) has achieved intrinsic fascination in the last few years. The use of an IL as environmental friendly solvent, offers many advantages over traditional materials synthesis methods. The change from molecular to ionic reaction media leads to new types of materials being accessible. Room-temperature IL have been found to be excellent media for stabilising transition-metal clusters in solution and to crystallise homo- and heteronuclear transition-metal complexes and clusters. Furthermore, the use of IL as solvent provides the option to replace high-te

Abstract:

Following the discovery that a single molecule can behave as a magnet, the field of research on magnetism has become of great interest to scientists. A large number of polynuclear compounds have been produced and studied worldwide over the past two decades, in an effort to obtain better single molecule magnets (SMMs). The synthesis of such compounds involves mainly first row transition metals and a wide range of bridging ligands.

Actuellement, seules quelques études in-situ ont été réalisées pour rationnaliser la synthèse des MOFs, comme des suivis par résonance magnétique nucléaire, par spectroscopie de masse ou par diffraction des rayons X en dispersion d'énergie.

Abstract:

This thesis documents the successful syntheses of six novel 2,2':6',2"-terpyridine-amine based polydentate ligands and a range of mono-, di-, and polynuclear complexes derived from them. The ability of some dinuclear complexes to affect the rate of hydrolysis of the phosphate diester group in the DNA model compound, bis-p-nitrophenyl phosphate (BNPP) has also been explored. Owing to the presence of two potential ligating groups in each polydentate ligand, a number of dinuclear, tetranuclear and serendipitous supramolecular architectures have been produced and characterised during this research

Abstract:

This thesis deals with the applications of organopalladium and organochromium chemistry to the functionalisation of the benzopyran ring system, at a variety of oxidation levels. Section I demonstrates the functionalisation of 3-, 6-, and 8-bromochromones via palladium (0) insertion into the C-Br bond. The resultant arylpalladium species are shown to undergo addition to the least substituted end of a variety of olefins including methyl acrylate, acrylonitrile and styrene. Subsequent palladium-hydride elimination leads to overall palladium catalysed vinylation of the chromone and the synthesis o
