The goal of the project has been to determine the scope and the mechanistic features of reactions of sulfido bridged molybdenum complexes which are related to those observed for the hydrodesulfurization catalysts. In particular, the activation of molecular hydrogen by bridging sulfido ligands in neutral paramagnetic and diamagnetic complexes and in cationic derivatives has been investigated. The ability of these complexes to catalyze or promote C-X and C=X bond hydrogenolysis in cases where X = sulfur, oxygen, or halogen has also been studied. The results of these studies lend support to proposed mechanisms for the surface catalysts which postulate the chemisorption of hydrogen on sulfido sites to form SH ligands, the participation of SH ligands in substrate hydrogenation, and the promotion of carbon-heteroatom bond cleavage by Bronsted acids. 7 refs.
