The nitration of 2,4,5-Trimethylphenol, 3,4,6-Trimethyl-2-nitrophenol and their acetates

Abstract

Nitration with fuming nitric acid of 2,4,5-trimethylphenol (1a), its acetate (1b), 3,4,6-trimethyl-2-nitrophenol (2a) or its acetate (2b) gives the 3,4,6-trimethyl-2,4-dinitrocyclohexa-2,5-dienone (3) in high yield. Some transformations of this dinitro ketone (3) are described.
