The conformational preference of 2,2′-bisanilides was investigated by variable-temperature NMR spectroscopy, NMR titration and diffusion experiments, IR spectroscopy, computational analysis, and X-ray crystallography. The formation of a conformation having the two amide moieties linked by an intramolecular hydrogen bond was detected at low temperatures. The interconversion kinetics of the two conformational
通过变温NMR光谱,NMR滴定和扩散实验,IR光谱,计算分析和X射线晶体学研究了2,2'-双苯胺的构象偏好。在低温下检测到具有通过分子内氢键连接的两个酰胺部分的构象的形成。通过NMR线形分析确定了双构型双苯胺2的相互转化动力学。通过DMSO滴定,DOSY实验和空间因素,排除了通过分子间氢键连接的超分子的形成。
