method wb97xd and 6-311++g(d,p) as basis set was implemented to investigate the reaction products energetics parameters. The atomic charges were calculated and discussed in details using three different methods. The transition state search were implemented to estimate the Gibbs free activation energy barrier of the reaction to emphasis the experimental results.
摘要 3-thioxo-1,2,4-triazin-5-ones 1 和 4-amino-3-mercapto-1,2,4-triazin-5(4H)-ones 2 作为新型结构单元的合成效用双和聚(1,2,4-三嗪)通过烷基化与相应的双和聚(卤)化合物进行了研究。已经使用光谱数据证实了烷基化位点的预测。使用混合密度泛函方法 wb97xd 和 6-311++g(d,p) 作为基础进行理论计算,以研究反应产物的能量参数。使用三种不同的方法计算和详细讨论了原子电荷。实施过渡态搜索以估计反应的吉布斯自由激活能垒,以强调实验结果。
