Page/Page column 11, (2019/03/17)
The present invention relates to a process for the preparation of arylsulfonylpro- penenitriles. The reaction starting from arylsulfonyl iodides is catalyzed by light. The process is scalable, environmentally benign and provides the product in good yield.

α,β-Unsaturated carbonyl compounds underwent regiospecific iodosulphonylation with toluene-p-sulphonyl iodide or sodium toluene-p-sulphinate and iodine to afford products (2), which were stereoselectively dehydroiodinated by triethylamine to give β-sulphonyl derivatives (3).The reactivity of compounds (3) as cationic β-acylvinyl equivalents, tested with amines or thiophenol, gave compounds (4) resulting from a displacement reaction.
