Friedel−Crafts benzylation of arenes with benzylic alcohols using sulfonic-acid-functionalized hyper-cross-linked poly(2-naphthol) as a solid acid catalyst

Abstract

The porous poly(2-naphthol) was made-up by combining the 2-naphthol, dimethoxymethane as an cross linker in presence of FeCl3. Furthermore the polymer was functionalized with ClSO3H to get a dense acid catalyst. The reagent is active for benzylation of arenes with benzylic alcohols irrespective of the nature of substituted arenes. This catalyst is good active compared with other acid catalyst used for Friedel−Crafts benzylation.
