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)₂C[double bond, length half m-dash]S 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.
