Oxytrifluoromethylation of multiple bonds using copper catalyst under mild conditions
Oxytrifluoromethylation reaction of styrene derivatives and alkynes with external and internal oxygen nucleophiles, catalyzed by copper (I) salts under mild conditions, was developed. Direct formation of a β- trifluoromethylstyrene derivative from a styrene derivative was also achieved by the reaction in the presence of a Bronsted acid. Further transformation of the oxytrifluoromethylated products was conducted to demonstrate their utility. 2012 Elsevier Ltd. All rights reserved.
