A simple, efficient and a versatile method for the synthesis of 5-substituted-1𝐻-tetrazoles by a [3+2]-cycloaddition reaction of arylnitriles with sodium azide in DMF using ZrOCl2·8 H2O as catalyst has been developed. The reactions work well at 100°C and give the desired products in excellent yield. The examples studied include arylnitriles having electron donating as well as electron releasing groups on the arene nucleus.

Molecular iodine in the presence of potassium carbonate has been found to be an efficient and ecofriendly catalyst for the synthesis of polysubstituted dicyanoanilines from aldehydes, acetone and malononitrile under solvent-free thermal condition. The experimental procedure is simple, includes shorter reaction times (less than 10 min) and results in excellent yield of the products.
