1,4-Cyclohexanedione synthesis

13synthesis methods
2,5-Dicarbethoxy-1,4-cyclohexanedione has been prepared by the self-condensation of diethyl succinate by use of sodium or sodium ethoxide catalyst (with or without a solvent) and by reaction of ethyl 4-bromo-3-ketobutanoate or ethyl 4-chloro-3-ketobutanoate with sodium ethoxide in ethanol.
1,4-Cyclohexanedione has been prepared by hydrolysis and decarboxylation of 2,5-dicarbethoxy-1,4-cyclohexanedione by using concentrated sulfuric acid, aqueous alcoholic phosphoric acid, or water at 195–200°, and by peroxyvanadic acid oxidation of cyclohexanone.
