Carbon materials like activated carbon (AC) undergo chemisorption with O2 to give species with electron deficiency in the carbon skeleton and negative charge at the oxygen end that upon reaction with PPh3 and benzoic acid afford Ph3P═O. Whereas amine donors react with O2-chemisorbed AC and nucleophiles to give dehydrogenatively coupled products in 67–89% yields via the corresponding radical cation
碳材料如活性炭(AC)进行化学吸附带O 2在氧结束使得在与PPH反应以得到具有在碳骨架缺电子和负电荷物质3苯甲酸和得到博士3 P = O。胺供体与O 2化学吸附的AC和亲核试剂反应,通过相应的自由基阳离子和亚胺离子中间体,以67-89%的产率得到脱氢偶联的产物,而使用β-萘氧化物衍生物的反应得到相应的氧化偶联的联-2-萘酚产品的产率为68–95%。
