3-Cyano-4,6-diphenyl-2-(phenethylamino)pyridine

Abstract

Novel synthesis of a 2-amino-3-cyano-2,6-diphenyl pyridine by a one-pot multi-component reaction of 1,3-diphenylpropane-1,3-dione, malononitrile and phenethylamine in the presence of N-hydroxybenzamide and zinc chloride has been reported. The structure of the synthesized compound was assigned on the basis of its elemental analysis, 1 H-NMR, 13 C-NMR, IR and mass spectral data. X-ray structure analysis confirmed unambiguously the proposed structure. The photophysical properties (λ Abs., λ Flu.) in CH 3 OH, CH 3 CN, CH 2 Cl 2 and the emission spectrum of the new compound in solution and in the solid state are reported. © 2014 by the authors; licensee MDPI, Basel, Switzerland.
