monosubstituted 1‐aryl‐1H‐1,2,3‐triazoles was achieved in a one‐pot reaction from arylboronic acids and prop‐2‐ynoic acid or calcium acetylide (=calcium carbide), respectively, as a source of acetylene, with yields ranging from moderate to excellent (Scheme 1, Table 2). The reaction conditions were successfully applied to arylboronic acids, including analogs with various functionalities. Unexpectedly

Abstract Microwave-assistedone-pot quick synthesis to 1-monosubstituted 1,2,3-triazoles was achieved with good to excellent yields using the widely available arylboronic acids, sodium azide and 3-butyn-2-ols within 15 min. This method features high efficient and facile as organic azides, acetylene gas and harsh conditions were avoided. Graphic abstract Microwave-assistedone-pot quick synthesis to 1-monosubstituted
An efficient method for the synthesis of 1-monosubstituted-1, 2, 3-triazoles from 2-methyl-3-butyn-2-ol under copper catalyst conditions has been developed through a one-step one-pot sequence. This method provides a concise and efficient pathway to synthesize 1-monosubstituted-1, 2, 3-triazole derivatives in good to excellent yields.
The synthesis of 1-monosubstituted1,2,3-triazoles was achieved using azides and propiolicacid by copper-catalyzed clickcycloaddition/decarboxylation, which was easily carried out in N,N-dimethylformamide at room temperature or 60 ˚C with yields ranging from moderate to excellent. The reaction conditions were found to be successful for aryl and vinyl azide reactants, including analogues with various
