fabricated by the Friedel–Crafts alkylation of 2-naphthol has been functionalized with sulfonic acid to obtain a solid acid catalyst. The catalyst is applied for the protection of phenol, alcohols, thiols, amines and aldehydes with acetic anhydride at room temperature. The catalytic protection using the new solid acid is featured by achieving high yield at neat condition, needing no aqueous work-up and/or
通过 2-萘酚的 Friedel-Crafts 烷基化制备的超交联多孔聚(2-萘酚)已用磺酸官能化以获得固体酸催化剂。该催化剂用于室温下用乙酸酐保护苯酚、醇、硫醇、胺和醛。使用新型固体酸进行催化保护的特点是在纯条件下实现高产率,无需水处理和/或色谱分离,并显示出优异的回收效率,表明这种磺化多孔聚合物作为一种新的保护方案的潜力广泛的可持续化学反应。图形摘要已开发出一种高效且环保的方法来保护酚类、醇类、硫醇类、
