The structure of Isomeric 3 – 6 type triazolo-pyrimidinones and their N-methylated and N-benzylat-ed derivatives was elucidated. In spite of the good agreement between the carbonyl bonds of derivatives 3 – 6 (R1= CH3, R=H, Q=SCH3) and their structure the IR method did not prove to be characteristic in general for the above structures. In contrast to the results reported previously it was found that
阐明了Isomeric 3-6型三唑并嘧啶酮及其N-甲基化和N-苄基化衍生物的结构。尽管衍生物3-6的羰基键(R 1 = CH 3,R = H,Q = SCH 3)与它们的结构之间有很好的一致性,但是IR方法通常不能证明是上述结构的特征。与先前报道的结果相反,发现3-6型衍生物通过在中性溶液中拍摄的UV光谱得到了很好的表征。
