A three‐component alkoxycyanomethylation of alkenes is achieved using the iridium photoredox catalyst [fac‐Ir(ppy)3]. This catalytic radical difunctionalization accomplishes both alkylation and alkoxylation of alkenes in one pot. Various alcohols can serve as the alkoxy sources in this transformation. In addition, the introduced cyano group can undergo further transformations into various useful functional
使用铱光氧化还原催化剂[ fac -Ir(ppy)3 ]可实现烯烃的三组分烷氧基氰基甲基化。这种催化自由基双官能化可在一锅中完成烯烃的烷基化和烷氧基化。在这种转化中,各种醇可以用作烷氧基源。另外,引入的氰基可进一步转化成各种有用的官能团。
