実験手順

106 g (495 mmol) of methyl 2,2,4,4-tetramethyl-3,5-dioxohexanoate were added dropwise to a suspension of 19.8 g (495 mmol) of sodium hydroxide in 500 ml of dimethyl sulfoxide. The mixture was stirred at room temperature, treated with 500 ml of water and adjusted to pH 1 using hydrochloric acid, and the deposited precipitate was then filtered off with suction. After drying, 70 g (95%) of 2,2,4,4-tetramethyl-1,3,5-cyclohexanetrione were obtained.
