Abstract

An efficient metal-free synthesis of 1,1-dithio-1-alkenes from 1,1-dibromo-1-alkenes and thiols using a diazabicycloundecene/dimethyl sulfoxide system was developed. The method was found suitable for various 1,1-dibromo-1-alkenes. The synthesis was completed within 5-15 minutes at room temperature with moderate to excellent yields.
