We describe a novel photoredox hetero-coupling reaction of two C (sp3) radicals from aliphatic acids or BF3K salts. The kinetic differences in radical persistence provide cross-selectivity, using an organic photoredox catalyst and an oxidant with visible light. This method exhibits broad scope, including several examples constructing sterically hindered C(sp3)–C(sp3) bonds.
