The cobaloxime catalyst enables dehydrogenation to generate the formation of new olefins. The generality, good substrate scope and mild conditions are good features in the photoredox/cobaloxime catalysis protocol, and this method will provide new opportunities for the functionalization of more olefins.
描述了光氧化还原/钴肟共催化的α-酮酸和甲基丙烯酸酯的偶联反应,以获得烯丙基酮。如果没有钴肟肟催化剂,则会生成1,4-二羰基化合物。该钴肟肟催化剂能够脱氢以生成新的烯烃。通用性,良好的底物范围和温和的条件是光氧化还原/钴氧肟催化方案的良好特征,该方法将为更多烯烃的功能化提供新的机会。
