To a dimethylformamide solution (20 ml) of 6-(12-acetoxydodecyl)-2,3-dimethoxy-5-methylphenol (1.1 g) is added bis(salicylidene)ethylenediiminocobalt(II) (40 mg) and the mixture is stirred in oxygen streams at atmospheric pressure and temperature for 72 hours. The product is isolated as in Example 7 and recrystallized from etherhexane (1:1). The above procedure yields 6-(12-acetoxydodecyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone (0.84 g) as orange-yellow needles melting at 47° C.
