Recent advances in multicomponent synthesis of 5-substituted 1<i>H</i>-tetrazoles from aldehydes: catalytic methods and green chemistry approaches.

Electron-withdrawing groups (EWGs), such as nitro and halogens like chloro and bromo, generally result in higher yields, with a strong trend observed where the para -nitro group yields the highest at 90%.
