Here, we present a visible light-catalyzed hydroalkylation of aryl-alkenes affording C–C bonds using aryl-alkenes and alkyl iodides. We demonstrate the formation of various hydroalkylation products in excellent yields, with primary, secondary, and tertiary alkyl iodides being tolerated in the reaction. Mechanistic experiments reveal a pathway consisting of halogen atom transfer followed by a radical-polar crossover mechanism delivering the desired hydroalkylation products.

芳基烯烃的光催化加氢烷基化

在这里，我们提出了一种可见光催化的芳基烯烃加氢烷基化反应，使用芳基烯烃和烷基碘化物提供 C-C 键。我们以优异的收率证明了各种加氢烷基化产物的形成，反应中允许使用伯、仲和叔烷基碘。机械实验揭示了一个由卤素原子转移组成的途径，然后是自由基-极性交叉机制，提供所需的加氢烷基化产物。
