Abstract: A simple and novel route for the synthesis of new terphenyl derivative as well as oxidative aromatization of α,β-unsaturated cyclohexenone to the corresponding phenol derivative is developed. The present work involves the condensation of ethylacetoacetate with 4,4'-difluoro chalcone followed by the aromatization using chloramine-T in acetic acid to yield the title compound (3). The synthesized compound (3) is well characterized by IR, NMR, LCMS and elemental analysis.

Keywords: 4,4'-difluoro chalcone; cyclohexenone derivative; aromatization; chloramine-T; terphenyl derivative
