Stabilization of Cu2O nanoparticles on a 2D metal–organic framework for catalytic Huisgen 1,3-dipolar cycloaddition reaction

Abstract

We report a simple methodology for the stabilization of Cu₂O nanoparticles of size 2–4 nm on the polar pore surface of a 2D metal–organic framework, {[Zn(Himdc)(bipy)_0.5]·DMF} (1). For the first time, a Cu₂O@1a (1a: desolvated 1) composite has been utilized as a recyclable catalyst for the Huisgen 1,3-dipolar cycloaddition reaction of terminal alkynes and aliphatic/aromatic azides for the synthesis of 1,2,3-triazoles.
