  Abstract An efficient and simple method for the preparation of 5-arylamino-1H-tetrazole and 1-aryl-5-amino-1H-tetrazole derivatives is reported using aluminum(III) hydrogensulfate (Al(HSO4)3) as an effective heterogeneous catalyst from secondary arylcyanamides. Generally, when the substitution in arylcyanamide is strongly electron-withdrawing the position of equilibrium would shift toward the isomer

  摘要报道了以硫酸铝（III）（Al（HSO4）3）为有效多相催化剂制备5-芳基氨基-1H-四唑和1-芳基-5-氨基-1H-四唑衍生物的简便方法。来自仲芳基氰酰胺。通常，当芳基氰酰胺中的取代强烈吸电子时，平衡的位置将移向1-芳基-5-氨基-1H-四唑（B）的异构体，并且随着取代基的电子给体的增加，平衡的位置转移到5-芳基氨基-1H-四唑（A）的异构体上。本方法学具有几个优点，例如优异的收率，较短的反应时间，易于后处理和较绿的条件。

• Synthesis of arylaminotetrazoles by ZnCl2/AlCl3/silica as an efficient heterogeneous catalyst

  日期：2012.6

  Arylaminotetrazoles were efficiently synthesized from secondary arylcyanamides by application of ZnCl2/AlCl3/silica as a reusable heterogeneous Lewis acid catalyst. 5-Arylamino-1-tetrazoles can be obtained from arylcyanamides carrying electron-withdrawing substituents on the aryl ring, while with electron-releasing groups 1-aryl-5-amino-1-tetrazoles will be produced. The former isomer is also produced within longer reaction times (similar to 20 h) even with electron-releasing groups.
