摘要

1,2-二碳官能团化是有机合成中同时引入两个官能团的一种阶梯经济策略。在此，我们报道了通过氢原子转移（HAT）和氰基迁移对未活化烯烃的可见光驱动烷基氰化反应。机理研究表明，喹啉乙基自由基是一种有效的水合HAT催化剂，促进亲电烷基自由基的生成。该方法反应条件温和，与多种官能团的相容性好。

Alkylcyanation of unactivated alkenes via photoinduced hydrogen atom transfer and 1,4-cyano migration

1,2-Dicarbofunctionalization of alkenes represents a step-economical strategy for introducing two functional groups simultaneously in organic synthesis. Herein, we report a visible-light-driven alkylcyanation of unactivated alkenes via hydrogen atom transfer (HAT) and cyano migration. Mechanistic studies suggest that a quinuclidineboryl radical serves as an effective hydridic HAT catalyst, facilitating the generation of electrophilic alkyl radicals. This method features mild reaction conditions and good compatibility with a diverse array of functional groups.
