for ketone synthesis. As an important coupling partner, bench-stable and commercially available alkyl boronicacids are widely used in transition metal catalysis, but they are rarely utilized as radical precursors for acylative coupling reactions. Herein, we reported an energy-transfer-enabled radical acylation using free alkyl boronicacids via NHC/photo dual catalysis. This protocol could efficiently
