Methanol → 6-(9-Acetoxynonyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone

Participants

Reaction Steps

To a methanol solution (30 ml) of 6-(9-acetoxynonyl)-2,3-dimethoxy-5-methylphenol (1.1 g) are added pyridine (0.3 ml) and bis(salicylidene)ethylenediiminocobalt(II) (14 mg), followed by stirring in oxygen streams at atmospheric temperature and pressure for 72 hours. The reaction product is isolated as in Example 7 and recrystallized from hexane. The above procedure yields 6-(9-acetoxynonyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone as orange-yellow needles melting at 30° C.
