Functionalised C-azido-hydrazones (1) were prepared by treating the corresponding chloro-hydrazones (2) with sodium azide under phase-transfer conditions.Treatment of the hydrazones (1) with boiling benzene afforded 3,4,4a,5-tetrahydrotriazino6,1-

NEW PERSPECTIVES IN THE CHEMISTRY OF 1-AZIDOHYDRAZONES

Thermal decomposition of 1-azidohydrazones results in tricyclic products , probably arising from nitrene intermediates through an intramolecular cycloaddition to the ethylenic bond.
