잘 알려져 있지 않는 6-oxo-1,6-dihydro-1,2,4-triazine 유도체 합성을 시도하였다. 가능한 각 tautomer의 model화합물을 합성하고 이들의 UV Spectra를 물과 alcohol용매 상에서 비교하여 tautomeric 평형을 검토하였다. 기대했던 상당량의 6-hydroxy tautomer는 관찰되지 않고 대부분 6-oxo-tautomer로 용액상태에서 존재함을 알았다.
Synthesis of 6-oxo-1,6-dihydro-1,2,4-triazine derivatives was tried. The model compounds of the possible tautomers were synthesized. The tautomeric equilibrium of 6-oxo-1,6, dihydro-1,2,4-triazine derivatives was determined by comparing their UV spectra and those of model compounds. 6-oxo-tautomer was exclusively detected in water and alcohol solutions without observation of the expected 6-hydroxy tautomers.
