A new type of transesterification between aryl, heteroaryl, alkyl N-heteroarene-2-carboxylates and various aldehydes by C–H and C–O bondactivations has been developed for the synthesis of versatile carboxylates. A possible mechanism containing oxidative addition of acyl–O bond in parent ester and radical cleavage of sp2 C–Hbond in aldehyde is proposed.
