Herein, we reported a method for iron-catalyzed, visible-light-induced hydrosilylation reactions of electron-deficient alkenes to produce value-added silicon compounds. Alkenes bearing functional groups with different steric properties were suitable substrates, as were derivatives of structurally complex natural products. Mechanistic studies showed that chlorine radicals generated by iron-catalyzed ligand-to-metal charge transfer in the presence of lithium chloride promoted the formation of silyl radicals.
在此，我们报道了一种铁催化的、可见光诱导的缺电子烯烃的硅氢化反应方法，可生成有价值的硅化合物。具有不同空间位阻性质官能团的烯烃以及结构复杂的天然产物的衍生物都是合适的底物。机理研究表明，在氯化锂存在下，铁催化的配体到金属电荷转移产生的氯自由基促进了硅自由基的形成。
