1-Substituted 5-Aminotetrazoles: Syntheses from CNN3 with Primary Amines
摘要:
1-Substituted 5-aminotetrazoles were prepared 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 aminotetrazole in good yield. This protocol also was utilized in the syntheses of bis- and tris(1-substituted 5-aminotetrazole) derivatives.

A series of dense energetic N‐trinitroethyl‐substituted mono‐, bis‐, and tri‐5‐aminotetrazoles were obtained by reacting primary amines with in situ generated cyanogen azide, followed by the trinitroethyl functionalization that involves a condensation of a hydroxymethyl intermediate (prepared by a reaction with formaldehyde) with trinitromethane. These compounds were fully characterized by using multinuclear
Possible pathways of alkylation of 5-aminotetrazole with dihalo-substituted compounds and the alkylation products were studied.
