Description Results of comparative study for 3,3´-[(4-X-phenyl)methanediyl]bis(1H-indoles) synthesis starting from 4-X-benzaldehyde (X = H, OCH3, N(CH3)2, NO2, OH) and 1H-indole in dichloromethane solution at room temperature and catalyzed by cerium trichloride heptahydrate or by new resin supported Ce(III) catalyst are described. It was found that Ce(III) cations supported on weakly acidic macroporous low-cost industrial resin have at least the same or better catalytic activity as CeCl3.7H2O (or other mentioned catalytic systems) advantageously its easy separation for a recycling.
