The regioselective O-difluoromethylation of 1,3-diones was achieved via in situ generation of difluorocarbene from bromodifluoromethylating reagents in the presence of an organic base. A wide variety of difluormethyl enol ethers were obtained in good to excellent yields. The reaction mechanism is discussed based on ab initio calculations (kcal/mol).
