Abstract

Herein we disclose a photosensitized E→Z contra-thermodynamic isomerization of vinyl sulfones, employing SEGPHOS as a promoter. The reaction was performed successfully on 23 vinyl sulfones and was extended to three other olefins. Different mechanistic experiments were performed as well as photophysical studies.
