Abstract
A study of the symmetrisation reactions ot [PtR2L2] with [PtX2L2] to give [PtXRL2] has been made (R = Me, Ph, or CCMe; L = PEt3, PMe3, PMe2Ph, or AsMe3; X = Cl, I, NCS, NO2, or NO3). The dependence of the reaction rate and stereochemistry on the substituents R, X, and L has been studied and the reaction mechanism is discussed. The reaction of cis-[PtCl2(PMe2Ph)2] with cis-[PtMe2(PMe2Ph)2] to give cis-[PtClMe(PMe2Ph)2] is catalysed by [Pt2Cl4(PMe2Ph)2], but the catalyst is destroyed in a competing reaction with cis-[PtMe2(PMe2Ph)2] to give cis-[Pt2(µ-Cl)2Me2(PMe2Ph)2].
