A series of 1-sulfonyl-1-trifluoromethyl allenes were prepared for the first time from commercial available 2-bromo-3,3,3-trifluoropropene. Cycloadditionreaction of these trifluoromethylated allenes with nitrones occured readily under mild conditions, giving the corresponding trifluoromethylated isoxazolidines in high yields.

alpha-Trifluoromethylallenic phosphonates were prepared by the reaction of diethyl chlorophosphite (DECP) and 4,4,4-trifluorobut-2-yn-1-ols in the presence of Et3N. The iodocyclization of these fluorine-containing allenic phosphonates was achieved with iodine under mild conditions to give the corresponding trifluoromethylated oxaphospholenes in moderate to good yields.
