Studies on Pt-S bonds. Complexes of methylsulfanyl- and methylsulfynil-acetate, benzoate and phenolate with the diethylenetriamineplatinum(II) moiety

摘要

This paper reports on some complexes of formula [Pt(dien)(L-S)]~+, where dien is diethylenetriamine and L are methylsulfanyl- and methylsulfinyl-acetate, benzoate and phenolate. These ligands are monodentate and bound to Pt via the sulfur atoms. Reactions with guanosinemonophosphate (GMP) give, in all cases, [Pt(dien)(GMP)]~(2-), with GMP coordinated though the N(7) atom. The reactivities of the [Pt(dien)(L-S)]~+ complexes are compared with those of [Pt(en)(L-S,O)]~ (en, ethylenediamine), in which the ligands L are chelated to Pt via the sulfur and the carboxylato, or phenolato oxygen atoms.
