complementary method to Huisgen's metal‐catalyzed triazole synthesis is described using unactivatedketones and arylazides as the substrates and proline as an organocatalyst. Dramatic acceleration was observed for this reaction using microwave activation and high regio‐ and chemoselectivities were obtained for a wide range of ketones and arylazides (see scheme).
