trans — cis isomerism about the NH-CO rotational axis is discussed in relation to the steric effect of the R 2 group, Ph-Ph interaction and inter- and intra-molecular hydrogen bonding. In dilute solution, R 2 UPhCl exists in the trans or the out form, and RPhUPhCl in the cisform o -Chlorophenyl derivatives show a monomeric v (N-H) band at a wavenumber lower than that of the other derivatives and no
摘要 为了检验引入的氯原子的影响,研究了含有氯苯基的三取代脲 R 2 UPhCl 和 RPhUPhCl [U = NC(O)NH] 在 ν(NH) 区域的红外光谱。围绕 NH-CO 旋转轴的反-反-顺异构现象与 R 2 基团的空间效应、Ph-Ph 相互作用以及分子间和分子内氢键有关。在稀溶液中,R 2 UPhCl 以反式或反式存在,而顺式 RPhUPhCl 邻氯苯基衍生物在波数低于其他衍生物的波数处显示出单体 v (NH) 带,并且没有相关联的 v (NH) ) 在浓溶液或什至在饱和溶液中的条带。

A novel aryl C–N shiftrearrangement reaction to form alkyl diaryl ureas from facilely available FPSBA derivatives was developed. FPSBA selectively reacted with secondary alkyl phenylamines to afford unsymmetrical alkyl diaryl ureas in good yields through a vicinal SN2′ mechanism rather than the traditional isocyanate intermediate pathway.
开发了一种新型的芳基C–N移位重排反应,可从容易获得的FPSBA衍生物形成烷基二芳基脲。FPSBA通过仲S N 2'机理而不是传统的异氰酸酯中间体途径与仲烷基苯胺选择性反应,以高收率提供不对称的烷基二芳基脲。
