摘要

在室温下的非水介质中，首次观察到一系列质子化氮基（脂肪族和芳香族胺以及吡啶）与弱配位的四(五氟苯基)硼酸阴离子 [B(C6F5)4]- 的质子信号中 14N-1H 偶联的三重分裂模式。报告了离子配对、溶剂参数以及 δH、1JNH 和 pKa 值之间相关性的影响。

Series of Protonated Nitrogen Bases with a Weakly Coordinating Counteranion: Observation of the 14N–1H Spin–Spin Coupling

A distinguished triplet splitting pattern for the ¹⁴N–¹H couplings in the proton signals of a series of protonated nitrogen bases─aliphatic and aromatic amines, as well as pyridines─with the weakly coordinating tetrakis(pentafluorophenyl)borate anion, [B(C₆F₅)₄]⁻, is observed for the first time in nonaqueous media at room temperature. The effects of ion pairing, solvent parameters, and correlation between the δ_H, ¹J_NH, and pK_a values are reported.
