Synthesis and correlation of spectral properties of some substituted 1,3-diphenyl-2-propen-1-ones

Abstract

Seven arylideneacetophenones:1-(4-chlorophenyl)-3-phenyl-2-propen-1-one (1a), 1-(4-nitrophenyl)-3-phenyl-2-propen-1-one (1b), 1-(4-methoxyphenyl)-3-phenyl-2-propen-1-one (1c), 1-(4-methylphenyl)-3-phenyl-2-propen-1-one (1d), 1-(4-chlorophenyl)-3-(4-methoxyphenyl)-2-propen-1-one (1e), 1-(4-methylphenyl)-3-(4-methoxyphenyl)-2-propen-1-one (1f) and 1,3-di(4-methoxyphenyl)-2-propen-1-one (1g) were synthesized from the corresponding substituted acetophenones and benzaldehydes in presence of sodium hydroxide in aqueous ethanol. The structures of the compounds 1a-g were confirmed by their UV, IR, 1H NMR, 13C NMR spectral data.
