The study of the self-disproportionation of enantiomers (SDE) via gravity-driven achiral column chromatography of a series of N-fluoroacetylated amides derived from 1-phenylethylamine is described. The chromatographic experiments performed with N-fluoroacetylated amides confirmed, that the process of molecular association in solution leading to the SDE manifestation, is sensitive to the fluorine content
描述了通过重力驱动的非手性柱色谱法对一系列衍生自1-苯基乙胺的N-氟乙酰化酰胺进行对映体(SDE)自歧化的研究。用N-氟乙酰化酰胺进行的色谱实验证实,导致SDE表现的溶液中的分子缔合过程对氟含量和所用溶剂的类型敏感。因此,在两种不同的洗脱液中观察到相同化合物的两种相反的洗脱曲线。而且,与已建立的无氟N-乙酰基-1-苯基乙胺谱相比,带有全氟烷基的酰胺显示出相反的洗脱顺序。
