Metal-free Mizoroki-Heck type reaction: a radical oxidative coupling reaction of 2-chloro-dithiane with substituted olefins

摘要

An efficient metal-free Mizoroki-Heck type reaction of di- and tri-substituted alkenes with 2-chloro-dithiane has been developed under ambient pressure of air or using a relatively low loading of BF_3 ·Et_2O. This study represents a new environmentally friendly method for the syntheses of dithianyl-substituted alkene derivatives via a radical oxidative coupling process.
