A visible light-mediated heterogeneous photocatalytic cyanomethylarylation of alkenes with acetonitrile has been established using K-modified carbon nitride (CN-K) as a recyclable semiconductor photocatalyst. This protocol, employing readily accessible alkyl -hydroxyphthalimide (NHPI) ester as a radical initiator, allows the efficient construction of a broad array of structural diverse nitrogenous heterocyclic compounds including indolines, oxindoles, isoquinolinones, and isoquinolinediones.
利用K修饰的氮化碳（CN-K）作为可循环使用的半导体光催化剂，已实现了可见光介导的烯烃与乙腈的多相光催化氰甲基化反应。该方法使用易于获得的烷基 - 羟基邻苯二甲酰亚胺（NHPI）酯作为自由基引发剂，能够高效构建多种结构多样的含氮杂环化合物，包括二氢吲哚、氧化吲哚、异喹啉酮和异喹啉二酮。
