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[Mo₃₆(NO)₄O₁₀₈(H₂O)₁₆] ({Mo₃₆}). For the first time, a Cu₂O@{Mo₃₆} 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.
