predict SEs with an accuracy from ±0.01 to ±0.02 kcal/mol. The additive SEs were consistent with Wheeler and Houk's direct SE model. However, the indirect or polarization SE model cannot be ruled out as it shows similar levels of additivity for two to three substituent systems, which were the number of substituents in our model system. SE additivity also has practical utility as the SEs can be accurately
本研究的目的是通过实验测试静电取代基效应 (SE) 对芳烃堆积相互作用的可加性。使用可以采用偏移面对面芳香堆积几何结构的小分子模型系统评估 SE 的可加性。这些分子扭转平衡的分子内相互作用通过折叠/展开构象平衡的变化进行定量测量。检查了五种不同类型的取代基(CH3、OCH3、Cl、CN 和 NO2),范围从给电子到吸电子。测量了氯仿溶液中 21 个取代芳烃堆积天平和 21 个对照天平的分子内堆积相互作用的强度。观察到的稳定性趋势与添加剂 SE 一致。具体来说,附加 SE 模型可以以 ±0.01 到 ±0.02 kcal/mol 的精度预测 SE。附加 SE 与 Wheeler 和 Houk 的直接 SE 模型一致。然而,不能排除间接或极化 SE 模型,因为它显示了两到三个取代基系统的相似水平的可加性,这是我们模型系统中取代基的数量。SE 可加性也具有实际效用,因为可以准确预测 SE。这应该
