Oxygen → 6-(9-Hydroxynonyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone

참여 물질

반응 단계

To a dichloromethane solution (30 ml) of 6-(9-hydroxynonyl)-2,3-dimethoxy-5-methylphenol (1.8 g) are added pyridine (0.5 ml) and bis(salicylidene)ethylenediiminocobalt(II) (32 mg). The mixture is stirred in oxygen streams at atmospheric temperature and pressure. The reaction product is isolated as in Example 7 and recrystallized from hexane. The above procedure yields 6-(9-hydroxynonyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone (1.2 g) as orange-yellow needles melting at 45° C.
