functional‐group interactions with an arene dominate over those with an alkene, and that a π‐facial intramolecular hydrogen bond from a hydroxy group to an arene is favored by approximately 1.2 kJ mol−1. The strongest interaction observed in this study was with the cyano group. Analysis of the series of groups CH2CH3, CHCH2, CCH, and CN shows a correlation between conformational free‐energy differences
通过NMR光谱对分子平衡进行的比较研究表明,与芳烃的非共价官能团相互作用优于与烯烃的非共价官能团相互作用,并且约1.2 kJ mol有利于从羟基到芳烃的π界面分子内氢键- 1。在这项研究中观察到的最强的相互作用是与氰基基团。的序列组的CH的分析2 CH 3,CHCH 2,CCH和CN节目构象的自由能差和计算出的电荷在C之间的相关性α这些取代基的原子表示其π相互作用的静电性质。构象异构体自由能差的变化显示出对溶剂氢键受体参数β的线性依赖性。
