Abstract
Herein, we report the facile synthesis of various benzimidazoles and benzothiazoles by using the NH-MIL-125(Ti) MOF as an efficient oxidant-free heterogeneous catalyst with good yield. Adsorption of the substrate on the NH-MIL-125(Ti) MOF surface through electron deficient Ti sites initiates the reaction. The broad substrate scope and high reusability of this catalyst are attractive for synthesis of a wide range of medicinally active benzimidazole and benzothiazole derivatives.
