treatment of azoxybenzenes bearing electron-withdrawing substituents at 4,4′-positions with sulfuric acid gave the corresponding 2-hydroxyazobenzenes, together with 4′-substituted 4-hydroxyazobenzenes. The treatment of 4,4′-dimethoxyazoxybenzene with p-toluenesulfonic acid and acetic anhydride afforded 4,4′-dimethoxy-3-acetoxyazobenzene and 4,4′-dimethoxy-2-tosyloxyazobenzene as the main rearrangement products
用硫酸处理在 4,4'-位带有吸电子取代基的偶氮苯得到相应的 2-羟基偶氮苯和 4'-取代的 4-羟基偶氮苯。用对甲苯磺酸和乙酸酐处理 4,4'-二甲氧基偶氮苯,得到 4,4'-二甲氧基-3-乙酰氧基偶氮苯和 4,4'-二甲氧基-2-甲苯磺酰氧基偶氮苯作为主要重排产物。
