Polarisation by cationformation (e.g., by protonation or by oxocarbonium ion formation) exerts a distinct and systematic effect on the selectivity of radicalchlorination of aliphatic acids, amines, and alcohols. A qualitative correlation is demonstrated between the magnitude of deshielding of a given proton (as expressed by the downfield shift in the 1H n.m.r. spectrum) and its “deactivation” as
通过阳离子形成(例如通过质子化或通过氧代碳鎓离子形成)的极化对脂肪族酸,胺和醇的自由基氯化的选择性产生了明显而系统的影响。在给定质子的去屏蔽强度(由1 H nmr光谱中的低场位移表示)与它的“失活”之间存在定性相关性,该失活由氯原子对它的抽象速率降低表示。描述了一种方便的方法,用于制备新的和已知的脂族单-和多氯胺。
