SYNTHESIS AND CHARACTERIZATION OF ORGANOPLATINUM(II) DITHIOLATE COMPLEXES OF THE TYPE [PTAR(S S)(PMEPH2)]

The reaction of [Pt2Ar2(mu-Cl)2(PMePh2)2] with sodium, potassium or am monium salts of the dithio acids (arc SS) affords mononuclear complexe s of the type [PtAr(arc SS)(PMePh2)] (where Ar = Ph, C6H4Me-4 (tol); a rc SS = SSCOEt, SSCNR, (R = Me or Et), SSPR2 (R = OEt, O(n)Pr, O(i)Pr, O(i)Bu, O(s)Bu, Ph)). The latter complexes were characterized by elem ental analysis and nuclear magnetic resonance (NMR) (H-1 and P-31) dat a. These new complexes are inert to excess triphenylphosphine at room temperature.
