  cis-[PtRL2(SnMe3)]. When the latter complex (R = CHCH2) reacts with X2 or MeX further oxidative addition occurs exclusively at the platinum centre. Aromatic isonitriles (R′NC)co-ordinate to the platinum and give insertion products trans-[PtC(CHCH2)= NR′}ClL2] on heating or carbene complexes with NBunH2. The alkynyl trans-[Pt(CCPh)ClL2] also forms 1 :1 adducts with R′NC and carbene complexes therefrom, but no insertion

Halosilanes exhibited the following orders of reactivities:  for Me3SiX, X = Cl (no reaction) << Br < I, and for Me4-nSiCln, n = 1 (no reaction) << 2 < 3. The reactivities of platinum complexes increased in the order of Pt(PPh3)4, Pt[Ph2P(CH2)2PPh2]2 (no reactions) << Pt(PMe2Ph)4 < Pt(PMe3)4

  Reaction of [Pt(C2H4)(PR3)2](R = Ph or C6H4Me-4) with moderately bulky phosphines at low temperatures did not give the expected tris- or tetrakis-phosphine complexes. Instead, mixed-phosphine complexes of the type [Pt(C2H4)(PR3)(PR′3)](R′= C6H11, C6H4OMe-4, C6H4OMe-2, C6H4Me-4 or CH2Ph) were formed. With less bulky phosphines, chelating diphosphines or phosphites, mixed tetrakis complexes, many of them prone to disproportionation, were formed. The complexes were characterised by 31P and 195Pt NMR spectroscopy in solution.

  在低温下，[Pt(C2H4)(PR3)2](R = Ph或C6H4Me-4)与中等体积的膦反应并未生成预期的三膦或四膦配合物。相反，形成了类型为[Pt( )(PR3)(PR′3)]的混合膦配合物（R′= C6H11, C6H4OMe-4, C6H4OMe-2, C6H4Me-4或CH2Ph）。与体积较小的膦反应时，形成了配位的二膦或磷酸酯的混合四膦配合物，其中许多配合物易于发生不均匀化。该配合物通过31P和195Pt NMR光谱在溶液中进行了表征。
