One‐pot Synthesis of 3,5‐disubstituted‐2,6‐dicyanoaniline Derivatives using CoFe₂O₄@SiO₂@L‐Arginine as a Magnetically Nanocatalyst

Abstract

Herein, we report an appropriate procedure for the synthesis of 3,5‐disubstituted‐2,6‐dicyanoaniline derivatives through a condensation reaction of β‐nitrostyrenes, malononitrile and aldehydes using CoFe2O4@SiO2‐Arginine magnetic nanoparticles as a basic nanocatalyst. In this work, 3,5‐disubstituted‐2,6‐dicyanoaniline derivatives were synthesized in good yields. This catalyst was characterized by FT‐IR, XRD, EDX, TGA, VSM and SEM analysis. Also, this nanocatalyst has advantages such as easy separation and reusability even after five runs without a significant reduction in its activity.
