The green synthesis of 2-amino-3-cyanopyridines using SrFe12O19 magnetic nanoparticles as efficient catalyst and their application in complexation with Hg2+ ions
AbstractIn this paper, a family of 2-amino-4,6-diphenylnicotinonitriles are prepared from aromatic aldehydes, acetophenone derivatives, malononitrile, and ammonium acetate via one-pot reaction catalyzed by SrFe12O19 magnetic nanoparticles. SrFe12O19 was an efficient, green, and reusable nanomagnetic heterogeneous catalyst with the average particles’ size of 70 nm which can be recycled and readily and
