Polyoxomolybdate-stabilized Cu2O nanoparticles as an efficient catalyst for the azide-alkyne cycloaddition

Abstract

We report a simple methodology for the stabilization of Cu2O nanoparticles of size 10-30 nm on the polar pore surface of the polyoxomolybdate (NH4)(12)[Mo-36(NO)(4)O-108(H2O)(16)] ({Mo-36}). For the first time, a Cu2O@{Mo-36} composite has been utilized as a recyclable catalyst for the Huisgen 1,3-dipolar cycloaddition reaction of terminal alkynes, aryl/alkyl halides and NaN3 for the synthesis of 1,2,3-triazoles.
