摘要: The complex [PtMe2(TPMA)] (1), TPMA=tris(2-pyridylmethyl)amine, contains bidentate TPMA with two free pyridyl groups. It reacts HX (X=CF3CO2, CF3SO3, BF4) at room temperature to yield [PtHMe2(TPMA)][X], which exists as an equilibrium mixture of isomeric forms, each containing fac-tridentate TPMA. major product has the hydride trans a group, but isomer in is amine. These cationic methyl(hydrido)platinum(IV) complexes are stable for several hours, undergo slow reductive elimination CH4 [PtMe(TPMA)][X], mer-tridentate. reaction 1 CF3SO3D CD3OD gives only CH3D, no deuterium incorporation into remaining methylplatinum and MeI it yields [PtMe3(TPMA)][I].
