Bis (1-trifluoromethyl-2, 2, 2-trifluoroethoxy) triphenylphosphorane (1) readily reacted with anilines to form N-hexafluoroisopropylated products (2). By the dehydrofluorination of 2, 2- arylamino-1, 1, 3, 3, 3-pentafluoropropenes (3) were obtained. Furthermore, when anilines with o-functional group were used as nucleophile, benzo-1, 4-dihetero-six membered rings that have CF 3 group at N-α-position were obtained.
