Lanthanum loaded CuO nanoparticles: synthesis and characterization of a recyclable catalyst for the synthesis of 1,4-disubstituted 1,2,3-triazoles and propargylamines

Abstract

A click and three component A³coupling reactions were achieved by lanthanum loaded CuO NPs under ultrasonication. 1,4-Disubstituted 1,2,3-triazoles and propargylamines were synthesized in a short reaction time with high regioselectivity and yields.
