Abstract:

The development of an economic and simple heterogeneous oyster shell waste supported CuCl2 catalyst for the aldehyde-alkyne-amine (A3) coupling reaction was reported. The waste oyster shell powder (OSP) supported CuCl2 (OSP-CuCl2) catalyst was prepared by a simple method from waste OSPs and CuCl2, which was shown to be a highly active and recyclable catalyst for the A3-coupling reaction. A range of propargylamines were obtained in good to excellent yields (85%-97%) under solvent-free and microwave-heated conditions. The OSP-CuCl2 catalyst can be simply recovered by filtration and reused for at least six runs. Propargylamine can be produced in 87% yield even when the scale of the A3-coupling reaction was increased to 150 mmol.
