Reaction of Thiofenchone or Thiochamphor with Disulfur Dichloride: Novel Formation of Tricyclic Polysulfanes

Abstract

Reaction of thiofenchone with disulfur dichloride gave trisulfane (15%) and tricyclic tetrasulfane (50%), all of which were Wagner-Meerwein rearranged products. Thiocamphor also reacted with disulfur dichloride to afford six- and seven-membered tricyclic polysulfanes. Selenofenchone also reacted with diselenium dibromide to afford diselenane and triselenane, both of which were Wagner-Meerwein rearranged products.
