efficient C−H acylation of azo‐ and azoxybenzenes with α‐keto acids has been developed by a combination of palladium catalysis and visible‐light photoredox catalysis at room temperature under 1.5 W blue LED irradiation. This method tolerates a variety of disubstituted azo‐ and azoxybenzenes, as well as α‐keto acids regardless of the nature of the substituents. A number of aryl ketones were obtained
