    • 1H NMR spectrum of 3 revealed the olefinic proton of the triazole ring at δ 7.49 ppm as a singlet, which confirms the regioselective formation of 3. When using Cu(II) salts, the olefinic protons signals at δ 7.42, 7.38 for 1,5- and 1,4-disubstituted 1,2,3-triazole isomers, respectively.

    • After extraction of the product by ether, the mother liquor was reused for the second run with the same substrates. The result of the first cycle and subsequent cycles gave the products in consistent yields (86%, 80%, 82% and 80%).
