Abstract:

A catalyst-free, smell-less and efficient synthesis of disulfanes was developed from the reaction of phenylhydrazines and elemental sulfur under air atmosphere. This new method could tolerate various functional groups such as —F, —Cl, —Br, —NO2, —CF3 and —MeO groups, and could be easily extended to the synthesis of other aryl disulfanes such as 2-naphthyl disulfane and 2-pyridyl disulfane. Compared with the reported methods, this new method required no transition metal catalysts, no stoichiometric amount of oxidants, and no smelly and sophisticated sulfur reagents, showing good practical value.

Key words: Disulfane, Phenylhydrazine, Elemental sulfur, Catalyst-free
