Dissociative substitution in four-co-ordinate planner platinium(II) complexes. The kinetic of sulphoxide exchange and its displacement by bidentate ligands in the reactions of cis- di(aryl)bis(dimethyl sulphoxide) platinum(II) in chloroform and benzene

Abstract

A parallel flow ¹H n.m.r. and u.v. spectrophotometric study of the exchange of Me₂SO with (CD₃)₂SO, and the displacement of Me₂SO by L–L [L–L = 2,2′-bipyridine, 1,10-phenanthroline, and 1,2-bis(diphenylphosphino)ethane] from cis-[Pt(Ph)₂(Me₂SO)₂] in CDCl₃ and benzene indicates that the main reaction path is dissociative with [Pt(Ph)₂(Me₂SO)] as the reactive intermediate.
