Mass spectral study of 2‐aryl‐4‐arylhydrazono‐4,5,6,7‐tetrahydro‐2H‐benzo‐1,2,3‐triazoles

Abstract

The mass spectra upon electron impact at 70 eV of the title compounds are examined. The fragmentation pattern of the tetrahydro‐benzotriazoles with unsymmetrically substituted the aryl groups in 2‐position and in hydrazone group cannot support the aspect for a mononuclear heterocyclic rearrangement.
