Boyland–Sims氧化

利用过硫酸钾在碱性条件下氧化苯胺，然后水解得到邻胺基苯酚的反应。氧化优先发生在邻位，有时会得到邻对位同时氧化的产物。苯酚类底物在相同条件下被氧化的反应被称为Elbs过硫酸盐氧化反应。Elbs氧化反应主要得到对位氧化产物。

【J. Am. Chem. Soc. 1967, 89, 2424-2428】

Aq K2S2O8 (27 g, 100 mmol) in 700 mL H2O was added dropwise over 1 h to a mixture of 3,4-dichloroaniline 4 (16.2 g, 100 mmol), pyr (100 mL) and 100 mL 2N KOH. After 15 h of stirring at r.t., decantation and evaporation at 45 ℃ in vacuo gave a solid which was triturated with Et2O(5 X 200 mL). The remaining solid was triturated with MeOH (5 X 75 mL) and the combined liquids were evaporated to afford 7 g (41%) of 5 + 6. Purification by reverse phase HPLC provided 385 mg of

5, and 541 mg of 6.
