MCM-41-SO3H: as an efficient reusable Nano-ordered heterogeneous catalyst for the synthesis of divers 1- & 5-substituted 1H-tetrazoles

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...
