Copper‐vitamin B₆ coated on maghemite nanoparticles: A new convenient dual catalysis system to synthesize α‐aminonitriles from benzyl alcohols

Abstract

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.
