Reactions of 1,4-Dimethyl-4-nitro-cyclohexa-2,5-dien-1-yl Acetates With Nitrogen Dioxide; the Formation of Polynitro Cyclohexenyl Esters

Abstract

Reactions of the epimeric 4-nitrocyclohexa-2,5-dienyl acetates (10) and (11) with nitrogen dioxide in acetic anhydride give closely similar mixtures of the nitro aromatic compounds (12)-(15), three polynitro nitrate esters (16)-(18), and two polynitro acetates (19) and (20). X-Ray crystal structure determinations are reported for compounds (16)-(18).
