Abstract

Abstract Michael type addition of halide ions (Cl− and Br−) to alkynyl (phenyl)-iodonium tetrafluoroborates (1) under acidic conditions proceeds in a completely stereoselective manner and affords (Z)-β-halovinyl (phenyl) iodonium halides (2), potential progenitors for generating α-haloalkylidenecarbenes, in high yields.
