|Abstract:||Trimethylamine N-oxide-initiated decarbonylation of M(CO)6 (M = Cr, Mo, W) followed by nucleophilic attack by 1,1′-bis(diphenylphosphino)ferrocene (dppf) affords a mixture of heterometallic products which consists mainly of a chelate with a bidentate diphosphine, M(CO)4(dppf), and a dinuclear phosphine-bridged complex M2(CO)10(dppf) at ambient temperature (28° C). The corresponding unidentate diphosphine, M(CO)5(dppf), is obtained as the major isolable product at 10° C. The IR and NMR (1H and 31P) spectral data and the structural properties of these complexes are presented and discussed. © 1989.|
