The mechanism of the thermal reactions of 1-aryl-5-methyltetrazoles, which involve isomerization to the azide, elimination of a nitrogen molecule, and formation of singlet nitrenes followed by isomerization to benzimidazoles and carbodiimides, has been studied by combinig the methods of derivatography and the current arsenal of mass-spectrometric techniques.The influence of the electronic properties of the substituent (in the para position of the benzene ring) on the course of the thermolysis has been established.
