摘要

After revisiting earlier works reporting the regioselective synthesis of 1, 5-disubstituted-1, 2, 3-triazoles via the addition of bromomagnesium acetylides to azides, much improved yields of the products were obtained for a wide array of azides and alkynes. The intermediates of that reaction can be trapped with different electrophiles to regioselectively form 1, 4, 5- trisubstituted 1, 2, 3-triazoles.
