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.
