摘要

我们报告了一种新颖的氰基迁移介导的自由基-极性交叉过程，该过程可同时实现脂肪烯的磺酰氰化和环丙烷的形成。在温和的光催化条件下，这种转化产生了多种多样的多取代环丙烷。机理研究阐明，反应是通过分子内亲核取代作用进行的，从而形成环丙烷衍生物。

Cyano migration-mediated radical-polar crossover cyclopropanation

We report a novel cyano migration-mediated radical-polar crossover process, whereby both the sulfonylcyanation of aliphatic alkenes and the formation of cyclopropanes are concurrently achieved. This transformation yields a diverse array of multi-substituted cyclopropanes under mild photocatalytic conditions. Mechanistic studies elucidate that the reaction proceeds via intramolecular nucleophilic substitution, leading to the formation of the cyclopropane derivatives.
