1-Substituted 5-Aminotetrazoles: Syntheses from CNN3 with Primary Amines.

[摘要]：1-Substituted 5-aminotetrazoles, e.g., I, were prepd. in situ by an excellent reaction of cyanogen azide and primary amines to generate an imidoyl azide as an intermediate in acetonitrile/water. After cyclization, the intermediate gave 1-substituted 5-aminotetrazole in a good yield. This protocol also was utilized in the syntheses of bis- and tris(1-substituted 5-aminotetrazole) derivs.
