The synthesis of alkyl boronicesters by direct decarboxylative radical addition of carboxylic acids to vinyl boronicesters is described. The reaction proceeds under mild photoredox catalysis and involves an unprecedented single-electron reduction of an α-boryl radical intermediate to the corresponding anion. The reaction is amenable to a diverse range of substrates, including α-amino, α-oxy, and
