## Abstract The dipolar cycloaddition reaction of allenyl perfluoroalkyl sulfones (**1**) to nitrones (**2**) was described. Unlike nonfluorineβcontaining allenyl sulfones, **1** reacted readily with **2** in ether at room temperature and unusual zwitterionic cycloadducts (**3**) were obtained in g
