monochloride (I-Cl) generation followed by iodination of aromatics using NCBSI/KI system has been developed. The NCBSI reagent requires no activation due to longer bond length, lower bond dissociation energy, and higher absolute charge density on nitrogen. The system is adequate for mono- and diiodination of a wide range of moderate to highly activated arenes with good yield and purity. Moreover, the precursor
已经开发了原位
一氯化碘 (I-Cl) 生成,然后使用 NC
BSI/KI 系统对
芳烃进行
碘化。由于键长更长、键解离能更低以及氮上的绝对电荷密度更高,NC
BSI 试剂无需活化。该系统适用于各种中等至高度活化的
芳烃的单
碘化和二
碘化,具有良好的收率和纯度。此外,前体N-(苯磺酰基)苯磺酰胺可以回收并转化为 NC
BSI,使该协议环保且具有成本效益。
