A ruthenium-catalyzed C(sp2)–H acyloxylation of 2-aroyl pyridine derivatives with simple sodium carboxylate utilizing transformable directing groups is described. This protocol features broad functional group tolerance and chemo- and regio-selectivity, providing the acyloxylation products in 45%-84%yield. Furthermore, the synthetic utility of this protocol was demonstrated by the late-stage functionalization
