Reaction of 1,3-dinitropropanes with acrolein under heterogeneous conditions (neat Al2O3) gives dinitrocyclohexanols, which, by treatment with potassium carbonate followed by acidic work-up, allow access to nitrocyclohexenone derivatives. The latter, by reaction with phenyltrimethylammonium tribromide, concludes a three-step synthesis of nitro-dibromophenols in satisfactory yields.

Abstract
Reaction of 1,3-dinitropropanes with acrolein under heterogeneous conditions (neat Al2O3) gives dinitrocyclohexanols, which, by treatment with potassium carbonate followed by acidic work-up, allow access to nitrocyclohexenone derivatives. The latter, by reaction with phenyltrimethylammonium tribromide, concludes a three-step synthesis of nitro-dibromophenols in satisfactory yields.File in questo prodotto:
