Abstract
The nitrations of 2,3,4-tribromo-5,6-dimethylphenol (9) and 3,4- dibromo-2,5,6-trimethylphenol (10) with fuming nitric acid in acetic acid give 2,5,6-trinitrocyclohex-3-enones in addition to 6-hydroxy-2,5-dinitrocyclohex-3-enones. X-ray crystal structure determinations are reported for the trinitro ketones (21) and (22), and the hydroxy dinitro ketones (23) and (24).
