A series of new bowl‐shaped N‐hydroxyimide derivatives has been designed and used as selective organoradical catalysts. A number of these bowl‐shaped N‐hydroxyimide derivatives exhibit excellent site‐selectivity in the amination of benzylic C(sp3)−H bonds in aromatic hydrocarbon substrates.

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
