Magnetically recoverable Cu2O–Fe3O4@TNT catalytic system for click chemistry in water: multi-component synthesis of 1,2,3-triazoles at room temperature†
The catalytic performance of a Cu2O–Fe3O4@TNT nanocatalyst derived from Fe(III) acetylacetonate, Cu(II) acetylacetonate and hydrogen titanate nanotubes (HTNTs) has been investigated for the first time for the click reaction in a water medium at room temperature. The nanocatalyst was characterized by performing XRD, HR-TEM, XPS, UV-DRS, H2-TPR, N2 adsorption-desorption, and ICP-OES analyses. The catalyst showed superior catalytic activity for the multicomponent synthesis of 1,2,3-triazoles in an aqueous medium. The nanocatalyst can be reused and recovered by using an external magnet.
