Alkyl‐ and aryl vinyl sulfones were obtained by eosin Y (EY)‐mediated visible‐light photooxidation of sulfinate salts and the reaction of the resulting S‐centered radicals with alkenes. Optimized reaction conditions, the sulfinate and alkene scope, and X‐ray structural analyses of several reaction products are provided. A detailed spectroscopic study explains the reactionmechanism, which proceeds

sulfonylation of styrenes with sulfonyl chlorides was developed for the synthesis of vinyl sulfones. The reaction proceeded under metal-free, mild and neutral conditions without extra oxidants or bases. It also exhibited good air and moisture tolerance, broad substrate scope and high chemo-selectivity, affording the vinyl sulfones in moderate to good yields.
