A concise synthetic strategy to alkynyl sulfides via transition-metal-free catalyzed C–S coupling of 1,1-dibromo-1-alkenes with thiophenols
摘要:
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.
