Highly efficient three-component synthesis of 5-substituted-1H-tetrazoles from aldehydes, hydroxylamine, and tetrabutylammonium azide using doped nano-sized copper(I) oxide (Cu2O) on melamine

Nano TiO2–H3BO3 as an efficient and recycable catalyst for the synthesis of 5-substituted-1H-tetrazoles

An efficient method for the synthesis of 5-substituted-1H-tetrazoles through the reaction of nitriles with sodium azide using titanium oxide–supported boric acid (TiO2-H3BO3) catalyst was reported. The reactions were carried out at 120 °C and provided the corresponding tetrazoles in good to excellent yields. This method displayed significant advantages ...

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...
