Perfluorinated Brønsted 'Superacids': Powerful Catalysts for the Preparation of Vitamin E
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)sulfo...
