journal contribution
posted on 20.09.2013, 00:00 authored by Xiaoqing Li, Xinhua Shi, Mingwu Fang, Xiangsheng XuHalosulfonylation
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.
