Аннотация: The UV irradiation of MH4L4 phosphine hydride complexes (M = Mo, W; and L represents tertiary phosphines) leads to the liberation of hydrogen and the formation of highly reactive incompletely coordinated species which react with N2 and CO to give the corresponding complexes, and also react with benzene and cyclohexane. We have proposed that these photochemically generated species are also capable of undergoing intramolecular deactivation with the transfer of a hydrogen atom from an alkyl substituent of the phosphine ligand and formation of a metal-carbon bond. In order to check this hypothesis, we studied the photochemical dehydrogenation of complexes with deuterated alkyl substituents in the ligands of WH4(PRPh2) 4, R = CD3 or C2D5.
