Photochemistry of phosphorus(III) complexes of bromocarbonyl(π-cyclopentadienyl)iron(II) and dicarbonylchloro(π-cyclopentadienyl)-molybdenum(II) and -tungsten(II)

Abstract

Photolysis with visible light in pyridine or dimethyl sulphoxide solutions of the complex [(cp)Fe(CO)LBr] yields [(cp)Fe(CO)2]2 when L = P(OPh)3 but [(cp)Fe(CO)2(PPh3)]+Br when L = PPh3(cp =π-cyclopentadienyl). Solutions of he complexes [(cp)M(CO)2LCl][M = Mo or W; L = P(OPh)3, PPh3 or P(C6H11)3] yield [(cp)M(CO)2Cl]2 on irradiation under similar conditions. Possible mechanisms for these photoreactions are discussed.
