Visible light‐induced decarboxylative sulfonylation of cinnamic acids with disulfides for the synthesis of vinyl sulfones was developed. The reaction underwent smoothly in the presence of Ru(Phen)₃(PF₆)₂ as a photocatalyst, Cs₂CO₃ as a base in DMSO at room temperature under blue LED (450–455 nm) irradiation and air atmosphere, generating the desired products in good yields. It provides an alternative route to vinyl sulfones with disulfides as sulfonylation reagent in the advantages of mild conditions, simple system and wide functional group tolerance.

通过可见光诱导肉桂酸与二硫键的脱羧磺酰化反应合成乙烯基砜

开发了可见光诱导的肉桂酸与二硫化物的脱羧磺酰化反应，用于合成乙烯基砜。在室温下，在蓝色LED（450-455 nm）辐射和空气气氛下，在DMSO中，在Ru（Phen）₃（PF ₆）₂作为光催化剂，Cs ₂ CO ₃作为碱的条件下，反应平稳进行。所需产品，收率高。它以温和的条件，简单的系统和宽泛的官能团耐受性的优势，提供了一种以二硫化物作为磺酰化试剂替代乙烯基砜的途径。
