The three-dimensional structures of four stereoisomers of 2-phenyl-4-ethynyldecahydro-4-quinolinol were determined by PMR and IR spectroscopy. The IR spectra of axial alcohols with an axial γ substituent provide evidence for the existence of two equ

Amine-ammonium salt systems in the interpretation of PMR spectra

Autor: L. P. Krasnomolova, K. I. Khludneva, G. S. Litvinenko

Publikováno v: Chemistry of Heterocyclic Compounds. 19:1210-1212

The stepwise protonation of amines can be utilized for the interpretation of the PMR spectra of conjugated pairs consisting of an amine and its salt. A linear dependence of the proton chemical shifts on the composition of the amine-salt system has be
