Synthesis and application of silica phenyl sulfonic acid as a solid acid heterogeneous catalyst for one‐pot synthesis of 2‐aryl‐1‐arylmethyl‐1H‐1,3‐benzimidazoles and bis(indolyl)methanes in water
Journal of Heterocyclic Chemistry Vol. 48, No. 6, 1448–1454
چکیده
Abstract Silica phenyl sulfonic acid (SPSA) was prepared and effectively used in the one‐pot synthesis of 2‐aryl‐1‐arylmethyl‐1H‐1,3‐benzimidazoles from o‐phenylenediamine with aldehydes in water in the presence of tetrabutyl ammonium bromide with good to high yield. Also, SPSA was used as a catalyst for the synthesis of bis(indolyl)methanes in water. J. Heterocyclic Chem., (2011).
