The primary photochemical process for η5-C5H5M(CO)3X complexes (M = Mo, X = Br or I; M = W, X = Cl, Br, or I) at 366 or 436 nm is dissociation of a carbon monoxide ligand. Irradiations of benzene solutions containing triphenylphosphine lead stereospecifically to cis-(η5-C5H5)M(CO)2(PPh 3)X. Quantum yields vary as a function of irradiation wavelength (Φ366 > Φ436), central metal (ΦMo > ΦW) and halogen (ΦCl > ΦBr > ΦI) but are relatively insensitive to PPh3 concentration. The substituted complexes η5-C5H5Mo(CO)2(PPh3)X undergo cis ? trans isomerization and ligand-exchange reactions leading to η5-C5H5Mo(CO)(PPh3)2X and η5-C5H5Mo(CO)3X.
