Abstract
Tetrazolobenzotriazine compounds such as 7-chlorotetrazolo[4,5-C][1,2,3]benzotriazine are prepared by the reaction of the corresponding substituted 5-(2-aminophenyl)tetrazole with nitrous acid. These new compounds are useful as initiating explosives, propellants, and chemical blowing agents.
