important role of C(3)F(6)/SO(3) ratio, reactiontemperature and boron catalyst/SO(3) ratio on FAFS' yield and selectivity, as well as a wide variety of ionic and radicalreactions possible with FAFS. We focused our attention on reactions of FAFS with aliphatic and aromatic alcohols, acyl halides, halides, H(2)O(2), ketones and radicals whose synthesis and reaction mechanisms will be presented and discussed
