摘要:

AbstractMethylhydrazones (III) of aromatic aldehydes and ketones react with nitrile imines (II) to give 1,2,3,4‐tetrahydro‐s‐tetrazinesIV(1‐9) which exhibits “ring‐chain” tautomerism in solution. The extent of this tautomerism is dependent both on steric and electronic effects of substituent groups at C‐3 and C
