Abstract: A series of pentacarbonyl complexes of chromium and molybdenum with unicoordinated-diphosphines, M(CO)5(η1-P-P) (P-P = dppe, dppp, dppb) has been prepared by amine oxide-induced phosphine substitution of the binary carbonyls. The basicity of the pendant phosphine groups was demonstrated by their ready conversion to the diphosphine-bridged heterobimetallic complexes (OC)5M(μ-P-P)M′(CO)5 (M, M′ Cr, Mo, W; M ≠ M′) in the presence of M⊂CO)5(CH3CN). The complexes were characterized by IR and NMR (1H and 31P-{1H}) spectroscopy. © 1993.
