反応手順

To a solution (20 ml) of 6-(12-acetoxydodecyl)-2,3-dimethoxy-5-methylphenol (1.1 g) in dimethylforamide is added bis(salicylidene)ethylenediiminocobalt(II) (40 mg), and the mixture is stirred at room temperature in an oxygen gas stream at atmospheric pressure for 72 hours. The solvent is distilled off and the product is extracted with ether. The ether layer is washed with water and dried over anhydrous sodium sulfate, and solvent is distilled off to give crude crystals. Recrystallization from ether-hexane (1:1) gives orange-yellow needles of 6-(12-acetoxydodecyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone (0.84 g). m.p. 47° C.
