GRAPHICAL ABSTRACT ABSTRACT The mechanistic insight of the thermal 1,3-chlorine migration reactions of N-chloroacetanilides under neutral conditions has been investigated. The results indicate that the 1,3-chorine migration reaction is initiated by the radical reaction of the homocleavage of the Cl-N bond and subsequent radical combination of the Cl-C bond on the aromatic rings. The radical mechanism
图形摘要 摘要 研究了中性条件下 N-氯乙酰苯胺的热 1,3-氯迁移反应的机理。结果表明,1,3-氯迁移反应是由Cl-N键的均裂自由基反应和随后的Cl-C键在芳环上的自由基结合引发的。N-氯-N-(4-甲基苯基)乙酰胺在枯烯中的热重排验证了自由基机理。在自由基机制中生成盐酸后,通过酸催化重排和酸催化奥顿反应发生迁移。目前的结果提供了对不同条件下奥顿反应机理的全面理解。
