A novel and effective dual catalysis system, copper combined with pyridoxal phosphate, which is anchored in maghemite nanoparticles were designed and applied to synthesize α‐aminonitriles from benzyl alcohols. This catalytic system has the potential ability to perform oxidation reactions and subsequently synthesize alpha‐amino nitrile in a reaction environment. Thus, the purpose of this paper is introducing a heterogeneous, sustainable and recyclable catalytic system to perform reactions that require a transition metal catalyst and organocatalyst continuously to achieve a target molecule. The catalysis system is examined and investigated with seven useful analyses such as FT‐IR, TGA, VSM, SEM, TEM, XRD, and ICP.
