Some reactions of the binuclear organoplatinum complexes , where R = Me or Ph are described, and a new synthetic method for the complex with R = Ph is reported.The dimethylsulphide ligands are easily displaced by other ligands, L, to give cis-.When R = Me, reaction with MeI and Ph2PCH2PPh2, dppm, gives <2(μ-dppm)>, whereas when R = Ph, reaction with MeI gives <(PtPh2MeI)4>, which has been characterized as its adduct with 2,2'-bipyridine .The latter complex exists as a mixture of two isomers, though the reaction between and MeI initially gives only one isomer of , formed by trans-oxidative addition.The reaction of with hydrochloric acid yields a 1:1 mixture of and <(PtMe3Cl)4>, and it is suggested that this reaction involves an intramolecular methyl group transfer between the platinum atoms of the dimer.
