4-Iodo-1,2,3-triazoles were synthesised via azide-alkyne cycloaddition of alkynyl Grignard reagent and benzyl azide followed by iodination reaction. The aminocarbonylation and aryloxycarbonylation of 4-iodo-1,2,3-triazoles were carried out in the presence of various N- and O-nucleophiles, resulting in the corresponding triazole-based 4-carboxamides and 4-esters, respectively. Both high-yielding reactions were carried out under mild conditions (atmospheric CO pressure, 70 °C).
