The Reaction Mechanism of the Azide-Alkyne Huisgen Cycloaddition [PDF]
Phys. Chem. Chem. Phys., 2019, 21, 19281-19287, 2020 The azide-alkyne Huisgen cycloaddition has a key role in click chemistry and configures as powerful tool in pharmaceutical and medicinal chemistry. Although this reaction has already been largely studied, there is an ongoing debate about its mechanism. In this work we study the dynamical aspects of the process using metadynamics computer simulation. We

Synthesis of aryl-1H-1,2,3-triazoles via 1,3-dipolar cycloaddition
Orbital: The Electronic Journal of Chemistry, 2012 A series of Aryl-1H-1,2,3-triazoles were prepared from the reaction between aril-azide (1) with 1.5 equiv. of terminal alkynes (2a-o). The reactions carried out at room temperature and in the presence of CuI (10 mol%) in acetonitrile. The compounds (3a-o)
