A palladium-catalyzed ortho-acylation reaction of azoxybenzenes with α-oxocarboxylic acids was developed in the presence of K2S2O8. The established methodology provides a direct approach to obtain acylated azoxybenzenes in good yields.

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.
