Control of radical reactions by transition-metal complexes

The overall goal of this Ph.D. is to contribute to the conception, the synthesis and the characterisation of original homogeneous ruthenium-based catalytic systems (or heterobimetallic ruthenium-titanium systems), highly active and effective towards atom transfer radical addition (ATRA) and polymerisation (ATRP) of several representative vinyl monomers. As catalytic performances may be tuned by the nature and the structure of the ligands around the metallic core, we are intending to systematically elucidate (by NMR and electrochemistry) the relations between stereoelectronic ligands parameters and the catalytic activity. Microwave irradition is also considered as an unexpected heating source for performing radical reactions.
