Impregnated Copper Ferrite on Mesoporous Graphitic Carbon Nitride: A High‐Performance Heterogeneous Catalyst for A3‐Coupling Reaction

Abstract Combination of copper ferrite and graphitic carbon nitride (g‐C 3 N 4 ) provided an effective recyclable magnetic nanocatalyst to drive three‐component reactions of aldehydes, amines, and alkynes toward propargylamines. The reactions proceeded under external ligand‐ free and neat condition to afford the corresponding products in good to excellent yields and short reaction times. Main Text Paragraph.
