Reaction of the complexes [Ni(dpb)2][dpb = 1,4-bis(diphenylphosphino)butane] and [Ni(dpp)2][dpp = 1,3-bis(diphenylphosphino)propane] with RCOX (R = Ph or Et; X = Cl or Br) in benzene, in molar ratio 1 : 1, at room temperature, produces nickel(II)-acyl complexes. The spontaneous decomposition of these species produces nickel(II) dihalogenodiphosphino-complexes, nickel(0) monocarbonyldiphosphino-complexes

and aldehyde (or acetone when R = Pri) in 1 :1 :1 ratio, showing the peculiar reducing effect of alkoxide promoted by the chelating property of the phosphorus ligand. The reaction of NaOMe with [Ni(dcpe)Cl2][dcpe = 1,2-bis(dicyclohexylphosphino)-ethane] afforded mainly [Ni2(dcpe)3] when carried out in the absence of free diphosphine, and [Ni(dcpe)2] in the presence of free diphosphine. The reaction always
