N,N′‐Diiodo‐N,N′‐1,2‐ethandiylbis(p‐toluene sulfonamide) (NIBTS) is a good and new reagent for synthesis of 2‐arylbenzimidazoles and 2‐arylbenzothiazoles at room temperature under solvent‐free condition with good to high yield. Absence of solvent, short reaction times, non‐corrosive, operational simplicity and environmentally friendliness are the main advantages of this procedure.
Ñ,N' -Diiodo- Ñ,N' -1,2-ethandiylbis(p -甲苯磺酰胺)(NIBTS)是一个很好的和用于无溶剂条件下的2-arylbenzimidazoles并在室温下2-arylbenzothiazoles合成新的试剂产量高到高。该方法的主要优点是无溶剂,反应时间短,无腐蚀,操作简便和环境友好。
