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.

reactivity and lead to distinct bond-forming modes. Herein we describe a rarely studied cycloaddition between nitrileoxides and electron-rich alkynes with reversed regioselectivity, leading to the useful 4-heterosubstituted isoxazoles. The use of a ruthenium catalyst completely overrides the inherent polarity of nitrileoxides. This reversed regioselectivity was also observed for their reactions with a range
