摘要

An efficient C-H acylation of azo- and azoxybenzenes with -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 -keto acids regardless of the nature of the substituents. A number of aryl ketones were obtained in good yields under mild reaction conditions.
