A facile and general route to 3-((trifluoromethyl)thio)benzofurans and 3-((trifluoromethyl)thio)benzothiophenes

Jie Sheng, Congbin Fan, Jie Wu

Abstract

A facile and general route to 3-((trifluoromethyl)thio)benzofurans and 3-((trifluoromethyl)thio)benzothiophenes is reported. The reactions of trifluoromethanesulfanylamide with 1-methoxy-2-alkynylbenzenes or methyl(2-alkynylphenyl)sulfanes promoted by BiCl3 proceed smoothly with broad functional group tolerance.
