Abstract

The isomerisation of the acyl chelate complex [W{C(O)C(CO 2Me):C(CO2Me)SR}(CO)2(?-C5H 5)] into [W{C(CO2Me):C(CO2Me)C(O)SR}(CO) 2(?-C5H5)] (R = Me or Pri), which involves a 1,3 shift of the SR group, has been shown to proceed via the mercapto vinyl complex [W{s-C(CO2Me):C(CO2Me)SR}(CO) 3(?-C5H5)], illustrating that the mechanism involves deinsertion of the acyl carbon monoxide followed by apparent insertion of co-ordinated CO into the C-S bond of the vinyl ligand.
