A facile and efficient procedure for the deoxygenation of sulfoxides to sulfides with the HfCl₄/Zn system

Abstract

Treatment of sulfoxides with the HfCl₄/Zn system in acetonitrile at room temperature has been shown to provide the corresponding sulfides in high yields. This new methodology is highly chemoselective, tolerating several functional groups such as –Br, –Cl, –OCH₃, –CHO and double bond.
