A 1,3-Nitro migration in the reaction of nitrogen dioxide with 2-t-butyl-4,6-dimethyl-4-nitrocyclohexa-2,5-dienone
Abstract
The formation of the 2-t-butyl-4,6-dimethyl-4,5,6-trinitrocyclohex-2-enones (2) and (3) on reaction of 2-t-butyl-4,6-dimethyl-4-nitrocyclohexa-2,5-dienone (1) with nitrogen dioxide proceeds via 4,5-addition of nitrogen dioxide to the 6-nitrocyclohexa-2,4-dienone (5), the product of a 1,3-nitro migration.
