A new and efficient transition metal-free oxidative cross-dehydrogenative coupling (CDC) reaction is described for the preparation of 4-aroylcoumarin derivatives. In this protocol aldehydes have been used as acylating agents for acylation of 3-substituted coumarins through C(sp2)-C(sp2) bond formation using the K2S2O8/Aliquat 336 system as an inexpensive and environmentally friendly reagent. The reactions proceeded in acetonitrile at 80 °C for 2-3 h to afford the corresponding 4-aroylcoumarin derivatives in high yields.

A facile and efficient palladium-catalyzed carbonylation of coumarins involving two C-C bond formations has been developed. The C-H bond oxidative functionalization proceeds through aroylation with insertion of carbon monoxide to give arylcoumarin ketones

The transformation of a hydroxyl into an acyl group, a transformation which has been extensively investigated on the benzene nucleus of several substrates, is now applied successfully for the first time to a heterocyclic ring and specifically to the pyron
