Series of Protonated Nitrogen Bases with a Weakly Coordinating Counteranion: Observation of the 14N-1H Spin-Spin Coupling
{{output}}
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)... ...
