Thermally Induced Fragmentation and Cyclisation of C-Azidohydrazones

C-Azidohydrazones 2 were synthesized from the corresponding C-chlorohydrazones 1 and submitted to thermal decomposition in boiling benzene.Various kinds of products were obtained due to competitive modes of evolution of first-formed nitrenes 13, namely hydrogen abstraction to form aminohydrazones 3 and benzotriazepine 8, and radical fragmentation to give ultimatively diaryls 4 and arylglyoxylate arylhydrazones 5.Ring-closed products, namely 1,2,4-triazoles 6 and imidazolones 7 were also formed.

Reaction of Hydrazonoyl Halides with N-Aryl Substituted Benzamidines

The reaction between hydrazonoyl halides and N-arylbenzamidines leads to the simultaneous formation of products derived from a substitution and a cycloaddition reaction via two independent paths.
