Abstract

The [3 + 2] cycloaddition of organometallic between nitriles and diverse form of azides was reported as common method for synthesis of tetrazoles which was recently studied via homogeneous and heterogeneous catalytic systems.1 The ligands have inevitable role on the efficiency of metal catalysis. In this area, various copper/ligand catalytic systems were reported. The organosulfur-based ligands are one of the most important compounds which recently reported as a best functional group in coordination chemistry. Due to presence of nitrogen and sulfur atoms, these compound can be generate complex with different metals as a soft donor ligand.2 In the present study, we have used SBA-15 silica mesoporous as a support for in-situ generation and stabilizing of Cu(I) species. The channels of SBA-15 were modified with organosulfur groups. This promising ligand into the SBA-15 led to the porous support with reductive nature. These well stabilized Cu(I) species into the nano-channels of SBA-15 were used for synthesis of various tetrazoles from sodium azide and aryl nitriles under green mild aqueous reaction conditions (Fig. 1).
