Complexes underwent competing isomerisation reactions, one an intramolecular construction of a vinyl aryl ketone which remains co-ordinated, the other a simple redistribution of the ligands around the metal.Product ratios are determined by kinetic rather than thermodynamic factors.For a sequence of complexes with L = L' = PMe2Ph, electron-releasing substituents on the vinyl ligand favour formation of ketone complexes, whereas similar substituents on the phenyl ligand have the reverse effect.Increasing the reaction temperature disfavours ketone complex formation.Mechanisms involving initial migration of either the vinyl or the aryl ligand are discussed on the basis of these results and a complementary study involving trapping of the likely acyl intermediates.
