Reduction of electron‐deficient alkenes enabled by a photoinduced hydrogen atom transfer
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
