title: Iron halide-mediated regio- and stereoselective halosulfonylation of terminal alkynes with sulfonylhydrazides: synthesis of (E)-β-chloro and bromo vinylsulfones.
abstract: Halosulfonylation of terminal alkynes was achieved with sulfonylhydrazides as the sulfonyl precursor and inexpensive iron halide as halide source in the presence of TBHP, allowing the regio- and stereoselective generation of (E)-β-chloro and bromo vinylsulfones.
