A process for producing 1H-tetrazoles represented by general formula (II) (wherein R represents an arbitrary substituent) from carbonitriles represented by the general formula (I): R-CN (wherein R is as defined above) with the use of a tetrazolating agent comprising an alkali metal azide and zinc chloride. The agent can be used in a variety of solvents and can fundamentally be applied to any carbonitriles. As zinc chloride is inexpensive, it contributes to cost reduction. |
