Intramolecular rearrangement of NN′-diaryldi-imidosulphur complexes of zerovalent platinum to a compound of bivalent platinum involving NS bond cleavage and concomitant hydrogen migration and N-C(aryl) bond formation; X-ray crystal structure of one of the products

Abstract

Reaction of Pt(PPh₃)₂(C₂H₄) with NN′-diaryldi-imidosulphur ligands affords the new compounds [Pt(PPh₃)₂(NN′-diaryldi-imidosulphur)](arylp-tolyl, p-chlorophenyl, or m,m′-xylyl), which rearrange, as shown by spectroscopy (n.m.r., i.r., u.v.) and a single-crystal structure determination, to a bivalent platinum complex by way of NS bond breaking, N–C(aryl) bond formation, and hydrogen migration.
