The catalytic activity of gel and macroreticular ion-exchange resins (Lewatit and Amberlyst-15) was evaluated for the reaction of benzene with benzyl alcohol and benzyl chloride at 80Β°C in the liquid phase. With benzyl chloride, the monobenzylation product, diphenylmethane, was obtained in low yield
Various solid acids were investigated for the liquid-phase benzylation of aromatics to industrially important substituted diphenylmethanes. Large-pore zeolites, particularly H-beta (BEA), were active and regioselective for the parasubstituted product in the benzylation of arenes. With deactivated ar
