Hojabri Department of Chemistry,Sharif University of Technology M.G. Dekamin Department of Chemistry,Iran University of Science and Technology Journal Article 2010 05 12 The catalytic activity of a mixture of ZnCl2: AlCl3 supported on silica gel was evaluated for the alkylation of phenols with benzyl alcohol, tret-butyl alcohol and styrene under microwave irradiation and solvent-free conditions. The catalyst preparation method, its characterization and reusability, were reported. The eect of the phenol to benzyl alcohol ratio and the time of reaction on the phenol conversion and distribution of products was investigated. A conversion percentage up to 97% was achieved when hydroquinone was used. A selective ortho- directed alkylation for phenol, -naphthol and -naphthol was observed. https://scientiairanica.sharif.edu/article_3270_3f7bcd0b3ea822683bba8fc530f151bd.pdf
