Abstract

Alkanal methylhydrazones react with nitrile imines to give 1,2,3,4-tetrahydro-s-tetrazines Tetrazines obtained from the reaction of nitrile imines with methylhydrazones of aromatic aldehydes and ketones exhibit ring-chain tautomerism in solution The extent or such tautomerism is influenced both by steric and electronic effects ot substituents.
