New derivatives of photochromic 2-aryl-1-(4-nitrophenyl)-1,1a-dihydroazireno[1,2-a]quinoxalines were synthesized by condensation of 4-methyl-and 4,5-dimethyl-1,2-phenylenediamine with 1,3-diaryl-2,3-dibromopropan-1-ones. The reactions of 4-methyl-1,2-phenylenediamine produce mixtures of regioisomers. The chemical properties of the reaction products were studied. The structure of one of the latter was established by X-ray diffraction.

Abstract The synthesis of α-bromo benzoylmethylene triphenylphosphorane 2 is firstly reported and α-bromo ylide 2 has sufficient activity to undergo Wittigreaction, affording a novel method for the stereoselective synthesis of α-bromo-α,β-unsaturated ketones 5.
