Doped Nano-Sized Copper(I) Oxide (Cu<sub>2</sub>O) on MelamineFormaldehyde Resin: a Highly Efficient Heterogeneous Nano Catalyst for ‘Click’ Synthesis of Some Novel 1<i>H</i>-1,2,3-Triazole Derivatives Having Antibacterial Activity
for the 1,3‐dipolarcycloaddition of organic azides with terminal alkynes catalyzed by doped nano‐sized Cu2O on melamineformaldehyde resin (nano‐Cu2OMFR) as a new and convenient heterogeneous catalyst is described. In this method, ‘click’ cycloaddition of various structurally diverse β‐azido alcohols and alkynes in the presence of nano‐Cu2OMFR in H2O/THF 1 : 2 furnished the corresponding 1,4‐disubstituted
