Photochemical reactions of RMn(CO)3L2 (R=H and CH3; L=P(OC6H5)3) and CH3Mn(CO)4L in benzene gave several kinds of orthometalated products, (x=0, 1, and 2).The reactions have been shown to proceed via ligand dissociation, CO and/or L, from the parent compounds and the resulting 16-electron intermediates activate a C-H bond of phenyl groups in triphenyl phosphite intramolecularly to yield orthometalated products.The results of photochemical reactions for MeMn(CO)3L2 and MeMn(CO)4L are compared with those of thermal reactions for these compounds.HMn(CO)4L was left intact by photochemical and thermal reactions.

Photochemical degradation of a series of tin-manganese bonded complexes was studied. The apparent reactivity of the tin-manganese bond toward UV irradiation is interpreted on the basis of absorption spectra of relevant complexes and available emissions from the light source. Two kinds of orthometalated products were obtained from photolysis of Me//3Sn-Mn(CO)//3 left bracket P(OPh)//3 right bracket //2 in benzene. Various kinds of experiments suggest that their photochemical reactions proceed through homolytic cleavage of the Sn-Mn bond in the initial stage and the resulting 15-electron intermediates abstract hydrogen from the triphenyl phosphite moiety. Molecular structures of the two kinds of orthometalated products, as clarified by X-ray structure analyses, are described.
