Abstract	A simple procedure to obtain 1,5-disubstituted 1,2,3-triazoles, using the catalytic system 13 erbium(III) trifluoromethanesulfonate, 1-methyl pyridinium trifluoromethanesulfonate and water 14 is described. The reaction proceeds through an eliminative azide–olefin cycloaddition (EAOC) 15 offering a highly regioselective approach and good yields (81–94%). The advantages of this method 16 include simple operations of work-up and the ability of the catalytic system to be re-used five times 17 without an evident loss in yield. 18
