Abstract

The Z-selective halosulfonylation of terminal alkynes has been achieved via the halosulfonylation of terminal alkynes by using sulfonohydrazides and copper(I) halides (CuI, CuBr and CuCl), which enables the generally applicable synthesis of halogenated vinyl sulfones with satisfactory efficiency.
