Unprecedented ortho-acylation of azoxybenzenes with α-oxocarboxylic acids by Pd-catalyzed C-H activation and decarboxylation

摘要

A palladium-catalyzed ortho-acylation reaction of azoxybenzenes with α-oxocarboxylic acids was developed in the presence of K_2S_2O_3. The established methodology provides a direct approach to obtain acylated azoxybenzenes in good yields.
