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
