5-(Azulen-1-yldiazenyl)tetrazoles; Syntheses and Properties

Abstract:

The tetrazole-5-diazonium salt, obtained by diazotizing 5-aminotetrazole in strong acid solution, was coupled with azulenes in the presence of pyridine to produce 5-(azulen-1-yldiazenyl)tetrazoles in good yields. The tetrazole moiety was monoalkylated in 1- and in 2- position using dimethyl sulfate for methylation and benzyl bromide for benzylation. The excess of alkylating agent generated in small amount tetrazole dialkylated salts. The synthesized compounds were characterized and some of their properties have been investigated, such as optical, magnetical and electrical.
