文摘

Disproportionation of nickel(I) bis(triphenylphosphino)bis(trimethylsilyl)amide, (Ph₃P)₂NiN(SiMe₃)₂, in the presence of bis(diphenylphosphino)amine, (Ph₂P)₂NH, yields Ni(II) and Ni(0) phosphinoamide complexes: [N(Ph₂P)₂]₂Ni (1), (Ph₃P)₂Ni[(Ph₂P)₂NH] (2). Ether solution, containing 2 and Ph₃P (1:2) reacts with dioxygen (one equivalent) to form triphenylphosphinoxide adduct (Ph₃P)₂Ni[(Ph₂P)₂NHOPPh₃] (3) in high yield. The crystal structures of compounds 1 and 3 have been determined by X-ray diffraction method.
