Dimethylformamide → 6-(6-Hydroxyhexyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone

Participants

Reaction Steps

To a dimethylformamide solution (20 ml) of 6-(6-hydroxyhexyl)-2,3-dimethoxy-5-methylphenol (1.5 g) is added bis(salicylidene)ethylenediiminocobalt(II) (15 mg), and the mixture is stirred in oxygen streams at atmospheric temperature and pressure for 72 hours. The reaction product is isolated as in Example 7 and purified by silica gel column chromatography. The ether-hexane (1:1) eluate yields 6-(6-hydroxyhexyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone (1.1 g) as orange-yellow oil.
