Abstract The 1H and 13C nuclear magnetic resonance spectra of N2,N4,N6-triphenethyl-1,3,5-triazine-2,4,6-triamine show features that suggest the hindered rotation about the carbon-nitrogen bond. A dynamic experiment was conducted at variable temperatures to determine the rotational barrier around this bond, which was also theoretically calculated and corroborated by density functional theory.

摘要 N 2 , N 4 , N 6 -triphenethyl-1,3,5-triazine-2,4,6-triamine的1 H 和13 C 核磁共振谱显示出表明碳-氮键旋转受阻的特征. 在可变温度下进行了动态实验,以确定该键周围的旋转势垒,这也得到了密度泛函理论的理论计算和证实。X 射线衍射分析证实了化合物的结构,并揭示了碳氮部分双键的特征,这是限制旋转的原因。正如预期的那样,红外光谱显示了特征带。最后,评估了该化合物的细胞毒性在体外针对人肝细胞癌细胞系并表现出良好的抗增殖作用。
