摘要：

The reactions of group IV halo trimethyl compounds with electron-rich Pt(II) complexes give facile oxidative addition of the M-X bond (M = Si, X = Br, I; M = Sn, X = Cl, Br, I). Equilibrium studies when M = Sn show that there is a pronounced thermodynamic favorability of the reactions with heavier halides, and it is this effect which makes isolation of silylplatinum(IV) complexes possible. The crystal structure of [PtIMe2(SiMe3)(2,2'-bipyridyl)] has been determined and shows an exceptionally long Pt-I bond arising from the strong trans influence of the trimethylsilyl group.
