N2  - Nitrations of phenols (3a), (3b), (7) and (8) with nitrogen dioxide in cyclohexane give similar patterns of reaction to those with fuming nitric acid in acetic acid. Nitration of 2,4-dibromo-3,5,6-trimethyl- phenol (19) with nitrogen dioxide gives isomeric trinitrocyclohex-3-enones (24), while fuming nitric acid reactions yield either the trinitro ketone (24a) and the cis-dinitro ketone (25) or the C2-epimeric ketones (25) and (26) depending upon the reaction conditions. Some reactions of these products are described, and the X-ray crystal structure of the epoxycyclopentene derivative (30) is reported.
