1-Aryl-3-nitro- and 3-Bromo-3-nitroprop-2-en-1-ones: Synthesis and Structural Features

A method for producing a number of ( E )-1-aryl-3-nitroprop-2-en-1-ones based on a synthetic condensation–dehydration strategy has been optimized. New ( Z )-1-aryl-3-bromo-3-nitroprop-2-en-1-ones have been synthesised from ( E )-1-aryl-3-nitroprop-2-en-1-ones using halogenation-dehydrohalogenation strategy to ( E )-1-aryl-3-nitroprop-2-en-1-ones. The fine structure of nitro- and bromonitroenketones and it’s features were determined by 1 H– 1 H NOESY NMR and X-ray diffraction analysis.
