| Abstract: | Summary 1-benzal-2-4-diphenyltetrazene is obtained in highest yields by reaction of benzalphenylhydrazone with benzene diaziniumchloride at pH 4–8. This reaction is reversed by treatment with hydrochloric acid. In pyridine or alcohol solution the tetrazene suffers an intramolecular transposition to triphenylformazane. |
