Popis: Polystyrene-divinylbenzene (5-7%) copolymer beads are combined with anhydrous gallium trichloride in CS2 to form a stable complex containing 3.06% Cl (equivalent to 0.287 mmol GaCl3/g complex beads). The complex showed good catalytic activity in organic synthetic reactions such as acetalation, esterification, ketal formation, etherification, and Friedel-Crafts alkylation. The catalyst can be reused several times without losing its activity and can be easily separated from the reaction mixtures.
