The synthesis of 2-perfluoroalkylated benzoxazolines and benzothiazolines was easily achieved under mild conditions in high yields and purity. The protocol uses readily available methyl 2-perfluoroalkynoates as fluorine-containing building block, and furnished the expected product in good to excellent yields in MeOH under reflux for 10 h. This novel synthetic protocol is efficient and general. A plausible
