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.

Thermal Sigmatropic Reactions: Overview
Sigmatropic shifts are classified based on an order term [i, j ], where i and j indicate the number of atoms across which each end of the σ bond migrates. Below are examples of a [3,3] sigmatropic shift in...

Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
