Selective alkylation of 2-pyridone could solve a challenge in chemistry and streamline the synthesis of important molecules. Here we report the regioselective O-alkylation of 2-pyridones by TfOH-catalyzed carbenoid insertion. In the catalytic system, alkylation of 2-pyridone was achieved with unprecedented regioselectiviy (>99 : 1). This protocol is characterized by mild reaction conditions, metal-free
