摘要：
The reaction of [Pt2X2(mu-Cl)(2)(PR3)(2)] with NaSpy or NaSepy gave complexes of the type [PtX(Epy)(PR3)](n) (X = Cl or Ar; E = S or Se; PR3 = PEt3, PMe2Ph, PMePh2 or PPh3; n = 1 or 2) which were characterized by elemental analysis and by H-1, P-31{H-1}, Pt-195{H-1} n.m.r. spectroscopy. When X = Cl a dynamic equilibrium between [Pt2Cl2(mu-Spy)(2)(PR3)(2)] and [PtCl(k-S,N-Spy)(PR3)] species exists in CHCl3 solution. The aryl derivatives, X = Ar, exist exclusively as dimers (n = 2) with predominantly (SN)-N-boolean AND bridging. The [Pt(Spy)(2) (PPh3)(2)] complex, prepared by reacting [PtCl2 (PPh3)(2)] with NaSpy, dissociates in CHCl3 to [Pt(k-S,N-Spy) (Spy)(PPh3)] and PPh3 at room temperature.
