An efficient method for the preparation of symmetrical disulfides using 1-butyl- 3-methylimidazolium hydroxide in aqueous medium

Abstract

In this study, a one-pot and efficient method is reported for the synthesis of symmetrical disulfides from alkyl halides in the present of sulfur and 1-butyl-3-methylimidazolium hydroxide as a basic reagent and phase transfer catalyst. The reaction proceeded very fast and afforded the desired products in moderate to excellent isolated yields.
