Dual Role of Alkynyl Bromides in One-Step Synthesis of Bromo-Substituted Alkynyl Sulfides

Abstract

An atom-economical and environmentally friendly method for synthesis of bromo-substituted alkynyl sulfides has been developed. In the absence of any additive, alkynyl bromides could react with tetrahydrothiophene to give bromo-substituted alkynyl sulfides in moderate to perfect yields.
