A mild and green strategy for the synthesis of selenoester derivatives has been developed through photoinduced decarboxylative coupling of α‐keto acids with diselenides. This transformation proceeds smoothly without requiring any external photocatalyst, additive, or oxidant. Both diaryl and dialkyl diselenides react efficiently with α‐keto acids to produce selenoesters in good yields. Mechanistic studies suggest that the generated acyl radical is responsible for this transformation.

α-酮酸与二硒化物的光诱导脱羧偶联形成硒酯


通过光诱导 α-酮酸与二硒酸的脱羧偶联，开发了一种温和的绿色合成硒酸衍生物的策略。这种转化可以顺利进行，不需要任何外部光催化剂、添加剂或氧化剂。二芳基和二烷基二硒化物都与α酮酸有效反应，以良好的产率生成硒酯。机理研究表明，生成的酰基自由基是这种转变的原因。
