Desulfurisation of trithiocarbonates at a dimolybdenum centre: an unexpected insertion into a co-ordinated alkyne
Abstract
On reaction with the dimolybdenum alkyne complex [Mo2{µ-C2(CO2Me)2}(CO)4(η-C5H5)2], dialkyl trithiocarbonates (RS)2CS were dismantled into sulfido (µ-S), thiolate (µ-SR) and CSR fragments; remarkably the last of these inserts into the middle of the alkyne to produce a dimetalla-allyl species with a µ-C(CO2Me)C(SR)C(CO2Me) ligand.
