ChemInform Abstract: REACTION OF 2-PHENYL-1-AZIRINE WITH COPPER BROMIDES. SELECTIVE FORMATION OF TWO TYPES OF BROMO-DIMERIC COMPOUNDS DEPENDING ON THE SOLVENTS

Treatment of 2-phenyl-1-azirine in cyclohexane with Cu(II) bromide afforded ω-bromoacetophenone azine, but in carbon tetrachloride gave 2-bromomethyl-2,4-diphenyl-2H-imidazole via 2-bromo-3,5-diphenyl-1,4-diazabicyclo[3.1.0]hex-3-ene.
