In this study, a new C(sp3)–H monofluoroalkenylation reaction involving cooperative visible-light photoredox catalysis and hydrogen-atom-transfer catalysis to afford products generated by selective hydrogen abstraction and radical–radical cross-coupling was described. This mild, efficient reaction shows high regioselectivity for the α-carbon atoms of amines, ethers, and thioethers and thus allows the
在这项研究中,描述了一种新的C(sp 3)-H单氟烯基化反应,涉及协同可见光光氧化还原催化作用和氢原子转移催化作用,以提供通过选择性氢提取和自由基-自由基交叉偶联反应生成的产物。这种温和,有效的反应显示出对胺,醚和硫醚的α-碳原子具有很高的区域选择性,因此可以制备带有各种取代基的单氟烯烃。该反应已应用于两个生物活性分子,表明其可用于具有惰性C(sp 3)-H键的化合物的后期单氟烯基化。
