An efficient and simple protocol for the construction of gem-difluoromethylenated 2-pyridones via difluorocarbene enabled ester insertion/acyl rearrangement of 2-acetoxylpyridines and (bromodifluoromethyl)trimethylsilane has been documented. The reactions feature transition-metal free, mild reaction conditions and excellent functional group compatibility. The late-stage modification of bioactive molecules
