Cu2O/nano-CuFe2O4: A novel and recyclable magnetic catalyst for three-component coupling of carbonyl compounds–alkynes–amines under solvent-free condition

• Cu2O/nano-CuFe2O4 magnetic composites were synthesized by a simple procedure.
• High catalytic activity was obtained for synthesis of propargylamines.
• The 42 products were produced in high yields.
• The magnetic composites take on favorable reusability.

Cu2O/nano-CuFe2O4 magnetic composite with different loadings of Cu2O has been synthesized by feasible and low-cost method. The as-prepared composite was fully characterized by FT-IR, XRD, FEG-SEM, EDS and VSM analyzer. The catalytic activity of magnetic composite for synthesis of propargylamines was evaluated. The catalyst has many obvious advantages and easily separated via an external magnet. It can be reused for five successive runs.
