Phenylboronic Acid/CuSO₄ as an Efficient Catalyst for the Synthesis of 1,4-Disubstituted-1,2,3-Triazoles from Terminal Acetylenes and Alkyl Azides. J. Mex. Chem.

The synthesis of 1,4-disubstituted-1,2,3-triazoles from alkyl azides and terminal alkynes at room temperature and under microwave heating was attained using Cu(I), generated in-situ from copper(II) sulfate and phenylboronic acid, as catalyst. Twelve new triazoles were obtained in moderate to good yields (53-98%), and the products were obtained by crystallization from the mixture reaction without further purification.
