Proton magnetic resonance spectra of pyridine 1-oxides and their conjugate acids was written by Abramovitch, Rudolph A.;Davis, John Bernard. And the article was included in Journal of the Chemical Society [Section] B: Physical Organic in 1966.Category: pyridine-derivatives This article mentions the following:
The proton magnetic resonance spectra of eleven pyridine 1-oxides (I) were measured in CCl4, D2O, and 18N deuteriosulfuric acid solution (corresponding to the neutral, hydrogen-bonded, and O-protonated species). The average downfield shifts for the α-, β-, and γ-proton lines have been calculated and the results are discussed. Electron distributions and coupling constants are compared with those of the corresponding pyridines and pyridinium salts. In the experiment, the researchers used many compounds, for example, 3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8Category: pyridine-derivatives).
3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Category: pyridine-derivatives
