Light-induced decarboxylative arylation was established by using readily available carboxylic acids and (hetero)aryl nitriles under alkaline conditions, without the need for photocatalysts, transition metals and oxidants. Preliminary mechanistic investigations demonstrated that the alkyl radical was generated through an electron donor–acceptor complex formed between carboxylates and aryl nitriles. Consequently, direct light irradiation of this complex yielded a diverse array of valuable 1,1-diaryl derivatives and benzylic amine derivatives in good to excellent yields.

通过电子供体-受体复合物对羧酸进行光诱导的脱羧芳基化反应


通过在碱性条件下使用现成的羧酸和（杂）芳基腈建立光诱导的脱羧芳基化，无需光催化剂、过渡金属和氧化剂。初步机理研究表明，烷基自由基是通过羧酸盐和芳基腈之间形成的电子供体-受体复合物产生的。因此，该复合物的直接光照射产生了多种有价值的 1,1-二芳基衍生物和苄胺衍生物，产率从良好到极好。
