One-pot multicomponent synthesis of ۲,۶-diamino-۴-arylpyridine-۳,۵- dicarbonitrilesusing prepared nanomagnetic Fe۳O۴@SiO۲@(CH۲)۳NHCO-adenine sulfonic acid

In this article, nanomagnetic Fe۳O۴@SiO۲@(CH۲)۳NHCO-adenine sulfonic acid was used as a simple,cost-effective, and reusable heterogeneous catalyst for the synthesis of ۲,۶-diamino-۴-arylpyridine۳,۵-dicarbonitriles by a one-pot-three-component condensation reaction of malononitrile, ammonium acetate, andaldehydes under solvent-free conditions at ۱۱۰ °C.
