Singly-bridging diphosphine complexes M2(CO)10(μ-dppp) (M  Cr, W; dppp  Ph2P(CH2)3PPh2) have been isolated in a facile synthesis via an oxidative decarbonylation of M(CO)6 using trimethylamine-N-oxide as the initiator. The thermal decomposition of these complexes, together with the molybdenum analogue, have been studied in refluxing acetonitrile, benzene or toluene under N2 or CO. The characterisations and thermal stabilities of these species are described and discussed. Conversion of the 1,3-bis(diphenylphosphino)propanedimetal decacarbonyl complexes of chromium, molybdenum and tungsten into the chelate M(CO)4(η2-dppp) is promoted by free dppp but inhibited by CO gas.
