Direct hydrogen atom transfer from a photoredox‐generated Hantzsch ester radical cation to electron‐deficient alkenes has enabled the development of an efficient formal hydrogenation under mild, operationally simple conditions. The HAT‐driven mechanism is supported by experimental and computational studies. The reaction is applied to a variety of cinnamate derivatives and related structures, irrespective of the presence of electron‐donating or electron‐withdrawing substituents in the aromatic ring and with good functional group compatibility.

减少由光诱导氢原子转移引起的电子不足的烯烃

氢原子从光氧化还原产生的Hantzsch酯自由基阳离子直接转移到缺电子的烯烃中，使得在温和，操作简单的条件下有效的正式加氢反应得以发展。HAT驱动的机制得到了实验和计算研究的支持。该反应适用于各种肉桂酸酯衍生物和相关结构，无论芳环中是否存在给电子或吸电子取代基且具有良好的官能团相容性。
