A copper(<scp>ii</scp>)–thioamide combination as a robust heterogeneous catalytic system for green synthesis of 1,4-disubstituted-1,2,3-triazoles under click conditions
An efficient and practical synthesis of 1,4-disubstituted-1,2,3-triazoles underclickconditions using a copper(II)–thioamide combination as an efficient heterogeneous catalyst is disclosed. Mild reactionconditions and high yields make this method an attractive option for the preparation of triazole derivatives. The key to this procedure was the generation of Cu(I) required for the azide-alkyne cycloaddition
