A series of propargylic amines were synthesized from terminal alkynes, dichloromethane and organic amines by using waste crab shell powders supported-CuI (CSPs-CuI) as catalyst. Using waste crab shell powders as catalyst support, not only resolve the problem of environment pollution and resources waste, but also produce propargylic amines through a highly efficient and green method. CSPs-CuI was characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TG) and atomic absorption spectroscopy (AAS). The reaction conditions were optimized by the investigation of catalyst support and base types. The propargyllic amines were obtained readily in intermediate to excellent yields under the optimal reaction condition. CSPs-CuI showed good reusability and could be recovered easily through filtration and washing. It was reused at least 4 times without obvious loss of catalytic performance.
