Abstract

1,3-Dipolar cycloaddition of azides to various electron-withdrawing group substituted acetylenes leading to triazole formation under mild conditions (reaction temperature around 55 °C or below) are reviewed. Furthermore, our efforts to lower the reaction temperature of cycloaddition of acetylenic amides with azides have also been discussed.
