Substituted metal carbonyls. XXIII. Syntheses of unicoordinated diphosphine complexes of Cr and Mo and their entry into heterobimetallics MM'(CO)10(μ-P-P) as metalloligands

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-) spectroscopy.
