全氟辛基磺酰氟 | perfluorooctyl sulfofluorure | 307-35-7 | C8F18O2S | 502.124 |
The key-step in the industrial synthesis of (all-rac)-?-tocopherol (synthetic vitamin E) is the condensation reaction of trimethylhydroquinone with the C20 building block isophytol. For this Friedel-Crafts-type reaction, perfluorinated NH- and CH-acidic compounds (perfluoroalkyl(aryl)sulfonyl imides and methides) have been applied as excellent catalysts, preferably in biphasic solvent systems.
