Substituent Effect on "Ring-Chain" Tautomerism of 1,2,3,4-Tetrahydro-s-tetrazines
Methylhydrazones (III) of aromatic aldehydes and ketones react with nitrile imines (II) to give 1,2,3,4-tetrahydro-s-tetrazines IV (1-9) which exhibit "ring-chain" tautomerism in solution.The extent of this tautomerism is dependent both on steric and elec

HETEROCYCLES FROM NITRILE IMINES. PART III. SUBSTITUENT EFFECT ON RING-CHAIN TAUTOMERISM OF 1,2,3,4-TETRAHYDRO-s-TETRAZINES
Selected series of 6-substituted 4-aryl-3-heteroaryl-1-methyl-1,2,3,4-tetrahydro-s-tetrazines (V:1-12) were synthesized via direct interaction between appropriate nitrile imine and model methylhydrazones.The extent of "ring-chain" tautomerism, as evidence
