A straightforward and efficient method for the regioselectivesynthesis of functionalized 1,4-disubstituted [1,2,3]-triazoles, from terminal alkynes and azides, has been established utilizing Cu(0) as the source of the catalytic species. The presumed catalytic Cu(I) species is generated by the combination of 10 mol % copper nanosize activated powder and 1 equiv of an amine hydrochloride salt. The addition
