This proposal will investigate (i) the catalytic reactivity of recently discovered N-heterocyclic carbene stabilised ruthenium-X (X = heteroatom) hydride complexes and (ii) new more reactive H-Ru-X systems including highly unsaturated 14-electron complexes. Overall the aim of the work is to establish a greater understanding of 'soft' metal-'hard' ligand interactions in catalysis, stoichiometric reactions and also physical inorganic chemistry.Thus Ru-H2O/EtOH/H2S/NR3 complexes will be tested as catalysts for ketone hydrogenation, nitrile hydrolysis and conjugate addition. Studies of RuOH/SH/NR2 complexes with both electrophiles and non-electrophiles will help realise possible applications of such complexes in known catalytic reactions, such as Wacker chemistry. Extension to new Ru-X complexes (X = H2, R3SiH) will be used to benchmark our heteroatom hydride systems against established (e.g. H2) and more exotic (R3SiH) ligand sets and show what can and cannot be bonded to our core Ru(carbene)2(CO) unit.Equilibrium and calorimetry studies will be used to further the understanding of soft-hard interactions and add credence or otherwise to the 1:1 model for late metal heteraoatom complexes. Finally, in the most adventurous part of the research plan, 14-electron heteroatom hydride complexes will be synthesised and studied; their high degree of coordinative unsaturation should allow access to new bond activation reactions.
