Abstract
DE LA CERDA-PEDRO, José Emilio; ROJAS-LIMA, Susana; SANTILLAN, Rosa and LOPEZ-RUIZ, Heraclio. 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. Soc [online]. 2015, vol.59, n.2, pp.130-136. ISSN 1870-249X.
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.
Keywords : triazoles; phenylboronic acid; CuSO4; Microwave irradiation.
