Crystal structure of 4-(naphthalen-2-yl)-2-oxo-6-phenyl-1,2-dihydropyridine-3-carbonitrile

Abstract

The synthesis and crystal structure of the title compound, C22H14N2O, are described. The title compound was synthesized by a three-component one-pot reaction in DMSO involving chalcone, cyanoacetamide and elemental sulfur as catalyst. The compound was characterized by spectroscopic methods and single-crystal X-ray diffraction. The structure consists of inversion-related dimers produced by N—H...O hydrogen bonding, which further interact through π–π contacts.
