| Abstract: | Copper(II)-exchanged hydroxyapatite, prepared by ion-exchanging of Ca(II) in calcium hydroxyapatite [Ca10(PO4)6(OH)2] with Cu(NO3)2 at 70 °C in water, functions as a reusable heterogeneous catalyst with neither reducing agents nor bases for azide-alkyne [3+2] cycloaddition at 50 °C in water under air. |
| Keywords: | Copper(II)-exchanged hydroxyapatite Azide-alkyne [3+2] cycloaddition Reusable heterogeneous catalyst Environmentally-benign process |
