Synthesis of platinum(II) alkyl and aryl complexes from K2[PtCl4] and tetraorganotin compounds in dimethyl sulphoxide

Colin Eaborn,   Kalipada Kundu  and  Alan Pidcock  

Abstract

Complexes cis-[PtR2(dmso)2] and cis-[PtRCl(dmso)2](dmso = dimethyl sulphoxide) are readily obtained from K2[PtCl4] and SnMe3R (R = aryl or Me) in dmso at 70–90 °C. Hydrogen-1 n.m.r. spectra show that the dmso ligands are bound through sulphur in solution and that the dmso ligand trans to R in cis-[PtRCl(dmso)2] undergoes dissociation and exchange at ambient temperature. With anionic reagents X–(X = Br, I, or SCN) the complex cis-[PtPhCl(dmso)2] forms bridged complexes [Pt2Ph2(µ-X)2(dmso)2]. In addition to the diaryl complex, SnMe3(C6H4OMe-2) forms the cyclometallated complex [[graphic omitted]H2-2)(dmso)2]. The dmso ligands of all the complexes are readily displaced by phosphorus donors, AsPh3, SbPh3, or 2,2′-bipyridyl; 31P-{1H} n.m.r. parameters are reported for the phosphorus-containing complexes.
