## Abstract The [3+2] cycloaddition of nonactivated terminal alkynes and trimethylsilyl azide proceeded smoothly in the presence of Cu^I^ catalyst and DMF/MeOH, to give the corresponding __N__‐unsubstituted triazoles in good to high yields. The reaction most probably proceeds through the in situ fo
