| 摘 要： | 报道了１，９－乙撑基蒽和１，９－乙撑基－１０－甲基蒽在ＣＨＣｌ_３／吡啶中与碘反应的机理。它们的单电子氧化生成游离基正离子，该过程存在侧链去质子和吡啶进攻蒽环两种竞争反应。蒽环上引入乙撑基使侧链氧化远比环氧化占优势。乙撑基比甲基容易去质子。

| Abstract: | The oxidation of aceanthracene and 9-methylaceanthracene by pyridine/iodine in chloroform was studied.During the initial electron transfer,the radical cation of aceanthracene underwent predominantly deprotonation of ethylene,less nucleophilic attack by pyridine.The crystal structure of aceanthracene-pyridinium adduct was determined by X-ray diffraction method.In the case of 9-methylaceanthracene,deprotonation leading to sidechain oxidation was the sole procedure.Deprotonation of ethylene was much more rapid than that of methyl. No trace ring-oxidation is observed. |
