The reaction of H2PtCl6 with nitrobenzene, o-nitrotoluene, benzoic acid, acetophenone and diphenyl in a CF3COOH/H2O mixture affords the anionic ?-aryl complexes of Pt^IV.In the case of monosubstituted benzenes, mixtures of meta- and para-platinated isomers were prepared. o-Nitrotoluene also gave rise to two isomers.Electron-withdrawing substituents decrease the rate of introducing the platinum moiety into benzene ring.
