Abstract

The photolysis of [(η⁵-C₅H₅)M(CO)₃]₂ (M = Mo, W) in solution at 25° leads to efficient homolytic M-M bond cleavage. Photolysis in CCL yields two molecules of the corresponding [(η⁵-C₅H₅)M(CO)₃Cl per molecule of the M-M bonded species with quantum efficiency for dimer disappearance in the range 0.12-0.45 depending on M and the photolysis wavelength. Simultaneous photolysis of M₂′(CO)10 (M′ = Mn, Re) and [(η⁵-C₅H₅)M(CO)₃]₂ yields (OC₅M'M(CO)₃(η⁵-C₅H₅) complexes with good chemical yield. The photochemistry is discussed in terms of lowest excited states involving the population of an orbital which is -antibonding with respect to the M-M bond.
