Covalent triazine frameworks (CTFs) were reported as heterogeneous catalysts for the oxidative coupling of benzylamines to imines. The CTFs with different monomers were characterized by TEM, XRD, FT‐IR, XPS, ICP etc. The CTFs showed good performances in various amines coupling and good stability for recycle reactions. High activities of the CTFs for amines coupling were attributed to the triazine structure and unique nature itself. ReactIR was used to investigate the catalytic process and two reaction routes were put forward according to the results.
