Abstract : Work has been focused on developing efficient methods of preparing 4-alkyl-nitrocyclohexadienones and 4-alkyl-4-nitrocyclohexadienols by batch and flow processes. Detailed studies of the thermal and acid-catalyzed rearrangements of 4-alkyl-4-nitrocyclohexadienones have been made, leading to mechanistic assignments that may have broader implications to the mechanism of direct nitration of reactive aromatics with nitronium ion. Similarly, the hydrolysis reactions of nitrodienols in both acidic and neutral aqueous media have been explored in detail. Studies of the reaction chemistry of nitrodienyl halides and nitrodienyl sulfonate esters have continued.
