An 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 in good yields under mild reaction conditions.

A palladium-catalyzed regio-selective acylation of C-H bonds of azoxybenzenes with alcohols was developed using tert-butyl hydroperoxide (TBHP) as an oxidant. Alcohol derivatives can act as effective acyl precursors in situ, which are less toxic, inexpensive, stable, and commercially available. These transformations proceeded smoothly and could tolerate a variety of functional groups. This journal is
