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.
在这里,我们展示了一种可见光催化的芳基烯烃的氢烷基化反应,该反应使用芳基烯烃和烷基碘化物生成 C-C 键。我们证明了各种氢烷基化产物的优异产率形成,其中伯、仲和叔烷基碘化物都能耐受反应。机理实验揭示了一条包括卤原子转移和自由基-极性交叉机制的途径,从而得到所需的氢烷基化产物。
