Group IVB organometallic sulphides. Part V. Reactions of lead sulphides with some electrophilic species and mercury compounds. Comparison of the reactions of aryl triorganolead sulphides with those of the other Group IVB sulphides

Abstract

Reactions of aryl triphenyl-lead sulphides, Ph₃PbSAr, with halogens, sulphur(II) halides, carbon halides, and mercury halides are reported. Unlike the analogous tin and germanium reactions, the reactions of the organolead sulphides do not lead exclusively to cleavage of the metal–sulphur bond. Ease of cleavage of the phenyl–lead bond, decomposition of organolead(IV) compounds to inorganic lead(II) species, and photochemical reaction with solvents, such as carbon tetrachloride, all make the organolead sulphide reactions particularly complex. Similiarities and differences in the reactions of R₃MSAr compounds, where R ≠ H, M = C, Si, Ge, Sn, and Pb are mentioned. Some bis(arylthio)lead reactions are also reported.
