A metal-free method has been developed for the direct thiolation of terminal alkynes with methyl sulfoxides, which affords various alkynyl sulfides. This transformation features excellent functional group tolerance, good stability in large-scale preparation and atom economy, which makes this reaction a practical method for the synthesis of alkynyl sulfides.

A novel synthetic strategy to alkynyl sulfides via transition-metal-free catalyzed C-S coupling of 1,1-dibromo-1-alkenes with thiophenols has been developed. The new strategy which avoided the transition-metal toxicities is environmental friendly and very important for alkynyl sulfides synthesis. (C) 2012 Elsevier Ltd. All rights reserved.
