1-Monosubstituted 1,2,3-triazoles have been prepared by a reaction of azides with vinyl acetate under microwave irradiation. Additionally, a microwave-assisted, two-step, one-pot procedure from halides involving azide substitution using TBAN3 in diethyl ether, followed by reaction with vinyl acetate, has effectively been employed.
