| Use | organic synthesis intermediates. used as pharmaceutical intermediates |
| production method | 2, 3-dichloro-5, 6-dicyano-1, 4-benzoquinone (DDQ) and 2, 6-di-tert-butyl-4-methoxyphenol were dissolved in methanol. Nitrogen was applied and the reaction was stirred for 12h. Concentrated under reduced pressure, the residue was treated with boiling benzene, and the insoluble matter of hydroquinone converted by DDQ was filtered out. After the filtrate was concentrated, a yellow solid was obtained, which was washed with aqueous methanol and filtered to obtain 2, 6-di-tert-butyl-1, 4-benzoquinone in 81% yield. |
