An operationally simple and mild visible-light, single-electron-transfer (SET), photoredox cross-coupling enables the synthesis of α-alkoxyketones in high yields from various aliphatic and aromatic acyl chlorides and structurally diverse potassium alkoxymethyltrifluoroborates. The bond connection is unique to both alkylboron chemistry and photoredox/Ni catalysis.
