This method has advantages of high yields, simple methodology, short reaction times and easy work-up. The catalyst can be recovered and reused in good yields. Graphical Abstract The arylaminotetrazoles were efficiently synthesized from the reaction of cyanamides and sodium azide in the presence of a catalytic amount of the nano In2O3. 1-Aryl-5-amino-1H-tetrazoles (B isomers) can be obtained from the arylcyanamides carrying electron releasing substituents on the aryl ring, while with the electron withdrawing groups, 5-arylamino-1H-tetrazoles (A isomers) are obtained.
