Novel Organosulfur Metal Complexes Derived from Dithioesters

Article abstract of DOI:10.1021/ja00287a031

Dithioesters react with complexes containing a metal-metal triple bond, in refluxing toluene or xylene, to give a novel class of organosulfur complexes.A single-crystal X-ray analysis of one such complex <(CH3C5H4)2Mo2(CO)2(SCCH3)(SC2H5)> confirms the presence of a symmetrically bridging thioacyl function, a bridging thioalkyl group, and a molybdenum-molybdenum single-bond distance of 2.806(1) Angstroem.When the reaction was effected at room temperature, a complex with a retained dithioester unit was obtained.As established by an X-ray analysis of , the thiocarbonyl group is bonded to one molybdenum atom with the sulfur atom also donor bound to the other metal atom.A semibridging carbonyl group is also present.
