Abstract

The migration of an alkylthio group across an enone ligand co-ordinated to tungsten has been demonstrated; X-ray diffraction studies have established the structures of the two isomeric products, one of which contains a novel alkyl-carbene ligand which functions as a three-electron donor to the metal.
