Silane- and peroxide-free hydrogen atom transfer hydrogenation using ascorbic acid and cobalt-photoredox dual catalysis

Abstract

Hydrogen atom transfer (HAT) hydrogenation of alkenes usually requires stoichiometric silanes and peroxides. Here, the authors report a silane- and peroxide-free HAT hydrogenation method using a combined cobalt/photoredox catalysis and vitamin C as a sole stoichiometric reactant.
