Direct photochemical cross-coupling between aliphatic acids and BF 3 K salts

We describe a novel photoredox hetero-coupling reaction of two C (sp ) radicals from aliphatic acids or BF K 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, incl...

Zusammenfassung:We describe a novel photoredox hetero-coupling reaction of two C (sp ) radicals from aliphatic acids or BF K 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(sp )-C(sp ) bonds.
