A series of phenyl azides bearing (E)-2-halovinyl groups were synthesized in high yields by treatment of (E)-3-(4-azidophenyl)- and (E)-3-(2-azidophenyl)acrylic acid with N-halosuccinimide in the presence of LiOAc. (E)-4-(2-bromovinyl) phenyl azide, one of the synthesized intermediates, was selected to transform to a diverse range of phenyl-1, 2, 3-triazoles bearing (E)-4-(2-bromovinyl) groups by Cu(I)-catalyzed 1,3-dipolar cycloaddition reaction.
