A Facile Stereoselective Bis‐Trifluoromethylselenolation Reaction of Alkynes with AgSeCF3 and N‐Bromosuccinimide

A facile stereoselective bis-trifluoromethylselenolation reaction of alkyne derivatives was realized for the first time. The reaction of alkyne derivatives and AgSeCF3 was found to proceed in the presence of N-bromosuccinimide and water in tetrahydrofuran and afforded bis-trifluoromethylselenolated products in moderate-to-excellent yields. The new methodology enables one-pot synthesis with a broad substrate range.
