Formation and Reactions of Novel Arylsulfido-Bridged Cyclic Organolead Compounds

Desulfurization of tetrathiaplumbolane 2 at 50 °C with three equivalent of triphenylphosphine afforded stable aryl(arylthio)-plumbylene and dithiadiplumbetane. The formation of these products is most likely interpreted in terms of generation of a novel arylsulfido bridged cyclic organolead compounds.
