Substituted metal carbonyls III. Chromium, molybdenum and tungsten tricarbonyl complexes containing bipyridyl and a unidentate diphosphine: facile synthesis via trimethylamine N-oxide-induced decarbonylations

The ability of trimethylamine N-oxide as a chemical initiator for facile oxidative decarbonylation in metal carbonyls is manifested by the isolation of M(CO)3(η²-bipy)(η¹-dppm) (where M = Cr, Mo, W; bipy = 2,2'-bipyridyl; dppm = bis(diphenylphosphino)-methane).The synthetic strategy and spectral (IR and 1H and 31P NMR) characterisations are presented and discussed.Syntheses of the well-known M(CO)4(η²-bipy) have also been modified to give high yields at ambient temperature.
