The Reactions of Some Substituted 2-Hydroxybenzonitriles with Nitrogen Dioxide: X-Ray Structures of 2-Cyano-t-6-hydroxy-3,4,5,6-tetramethyl-r-4,t-5-dinitrocyclohex-2-enone, 2-Cyano-3,4,5,6-tetramethyl-r-4,t-5,t-6-trinitrocyclohex-2-enone and 2-Cyano-c-6-h

Reaction of 2-hydroxy-3,4,5,6-tetramethylbenzonitrile (1c) with nitrogen dioxide gives predominantly the 4,5,6-trinitrocyclohex-2-enones (9) and (10a,b), with lower yields of the 4-nitro dienone (5a) and the 6-hydroxy-4,5-dinitrocyclohex-2-enone (6).React
