Electron-deficient molybdenum/cobalt/sulfido clusters: Chemistry related to hydrodesulfurization (HDS) catalysis

The author's work on the reactions of Cp2Mo2Co2S3(CO)4 (1) and Cp2Mo2 Co2S4(CO)2 (2) with organosulfur compounds is reviewed. Reaction pathways that lead to C S bond scission are proposed, and the relexance of these results to HDS reactions mer commercial “CoMoS” catalysts is discussed.
