Synthesis and Spectral Characterization of Some New 4-(2,6-Diarylpyridin-4-yl)-<i>2H</i>-chromen-2-ones

<div><p></p><p>Some new 4-(2,6-diarylpyridin-4-yl)-<i>2H</i>-chromen-2-one derivatives <b>5a–l</b> have been synthesized by reacting 4-(3-oxo-3-arylprop-1-enyl)-<i>2H</i>-chromen-2-ones <b>3a–c</b> with appropriate 1-(2-oxo-2-arylethyl)pyridinium bromide salt <b>4a–d</b> in the presence of ammonium acetate in refluxing glacial acetic acid. The newly synthesized compounds have been characterized by elemental and spectral analysis.</p> </div
