Solid superacid-catalyzed organic synthesis. 4. Perfluorinated resinsulfonic acid (Nafion-H) catalyzed Friedel-Crafts benzylation of benzene and substituted benzenes
摘要:
Nafion-H, a perfluorinated resinsulfonic acid, catalyzes Friedel-Crafts benzylation of benzene and substituted benzenes with benzyl alcohols under relatively mild experimental conditions. Reactions are clean, and water formed as a byproduct does not deactivate the catalyst. It was also found that this method is applicable to the intramolecular cycloalkylation and oligomerization of methoxybenzyl alcohols.
