REVERSIBLE CARBON-CARBON BOND FORMATION BY INTERCONVERSION OF CO AND μ-ACYL LIGANDS ON THE FACE OF AN OSMIUM CLUSTER

Article abstract of DOI:10.1016/0022-328X(85)87348-4

Addition of PMe2Ph to the μ-acyl complex (III) induces carbon-carbon bond cleavage with conversion of the μ-acyl group to a terminal CO ligand and gives the zwitterionic compound (IV).Facile elimination of CO (or PMe2Ph) from IV at the rhenium atom leads to the back formation of a μ-acyl group and gives the complex (V) or complex III.
