α‐Pyridylphenyl diazonium salts 2 were found to undergo valence bond isomerization and gave the new pyrido[1,2‐c]benzo‐v‐triazinium salts 3. The ir and nmr studies on the products showed that isomers 2 and 3 form an equilibrium, and the ring closure is favoured by electron withdrawing substituents.
