β-nitro-α-phenyl-propanes having methyl or methoxy substituants on the phenyl ring (37 compounds in all) are presented. The α and β protons of the side-chain give a pattern usually analyzable as ABX. The data are discussed in terms of correlations of coupling constants and chemical shifts with electronegativity of the substituent groups, steric and electronic effects, and apparent changes in rotamer
提供了来自苯环上具有甲基或甲氧基取代基的 β-氨基-、β-氨基盐酸盐-、β-羟基-和 β-硝基-α-苯基-丙烷(共 37 种化合物)的 pmr 光谱数据。侧链的 α 和 β 质子给出了一种通常可作为 ABX 分析的模式。根据偶联常数和化学位移与取代基的电负性、空间和电子效应以及旋转异构体群的明显变化的相关性来讨论数据。苯丙胺的氨基与苯环邻位上的甲氧基官能团之间的氢键适用于盐而不是游离碱。
