Montmorillonite KSF as a very efficient heterogeneous catalyst for the synthesis of 5-substituted 1H-tetrazoles
Montmorillonite KSF has been used as an effective and non-toxic heterogeneous catalyst for one-pot synthesis of 5-substituted 1H-tetrazoles via [3+2] cycloaddition of sodium azide with a wide variety of nitriles. The reaction afforded high yields of the desired products in a short reaction time under mild reaction conditions. The catalyst can be recovered by simple filtration and reuse...

متن کاملMontmorillonite: An efficient, heterogeneous and green catalyst for organic synthesis
Reactions of organic molecules on Montmorillonite clay mineral have been investigated from various aspects. These include catalytic reactions for organic synthesis, chemical evolution, the mechanism of humus-formation, and environmental problems. Catalysis by clay minerals has attracted much interest recently, and many reports including the catalysis by synthetic or modified clays have been pub...
متن کاملSynthesis of 2-arylbenzimidazole derivatives using nano montmorillonite clay as an efficient catalyst
Benzimidazoles are among the most important nitrogen-containing heterocyclic compounds that have many pharmaceutical applications, including antitumor, anticancer, anticorrosive, antibacterial, irritant and enzymatic interceptors. In this research, the synthesis of benzimidazoles by using o-phenylenediamine and aldehyde derivatives in the presence of the nano montemurillonite in solvent-free an...
