Synthesis of Chiral α-Aryl Ketones by Photoredox/Nickel-Catalyzed Enantioconvergent Acyl Cross-Coupling with Organotrifluoroborate

Photoredox/nickel-catalyzed enantioconvergent acyl cross-coupling of carboxylic derivatives with racemic secondary organotrifluoroborate was developed for the synthesis of an enolizable chiral α-aryl ketone under mild neutral conditions. Moderate to high yields and good enantioselectivities were achieved.
