An Efficient, Simple and Inexpensive Method for the Preparation of 1,4-Benzoquinone MonoketalsviaAnodic Oxidation of 1,4-Dimethoxybenzenes
摘要:
Anodic oxidation of a series of 1-substituted-2,5-dimethoxybenzenes gives 2-substituted-1,1,4,4-tetramethoxycyclohexa-2,5-dienes in almost quantitative crude yield. Selective monohydrolysis of these bis-ketals is possible in many cases, and gives 3-substituted-4,4-dimethoxycyclohexa-2,5-dienones in good to excellent overall yield.
