The synthesis of complexes of PH-functional diphosphanes (CO)mM(PhPH - PR2)n (M = Mo, m = 4, 5, n = 2, 1, R = Ph, tBu; M = Fe, m = 4, n = 1, R = Ph) (7 - 10) and of 1,2,3-triphenyltriphosphane (CO)mM - PPhH - PPh - PPhH - M(CO)m (M = Mo, Fe, m = 5, 4) (13, 14) is reported.The availability of PH-functional groups as well as uncoordinated P-atoms in these compounds permits the formation of new P - P-bonds and of heterometallic complexes such as (CO)5Mo(PhPH - PPh2)Ni(CO)3 (16) or (CO)5Mo - PPhH - PPhPPhH - Mo(CO)5 (17).The 1H- and 31P NMR spectra of the complexes 4 - 10 and 13 - 20 are discussed.For complexes of 1,1,2,3,3-pentaphenyltriphosphane, (Ph2P)2PPH - M(CO)m (M = Mo, Fe, m = 5, 4) the migration of the (CO)mM group from the medial to the terminal position of the P3-skeleton could be observed by means of 31P NMR spectroscopy.
