Description
Summary:[Display omitted] •Multicomponent synthesis of 1,2,3 triazoles from aromatic aldehydes, sodium azide and nitromethane.•Reusable catalytic heterogeneous system.•Microwave assisted synthesis. The acid properties of Al-MCM-41 and sulfated zirconia were used to develop a strategy for the synthesis of 4-aryl-NH-1,2,3-triazoles via a multicomponent reaction involving various benzaldehydes, sodium azide and nitromethane. The efficiency of the process is analysed from the perspective of the difference in acids among the catalysts used.
