Conclusions
-
1.
An analysis of the parameters of the NMR-13C and1H spectra of derivatives of 3-hydroxypyridine and their N-oxides showed that transition from the unoxidized base to the N-oxide is accompanied by a shift of practically all the signals into a higher-field region.
-
2.
The NMR data were compared with a calculation of theπ-charges of derivatives of 3-hydroxypy-ridine-1-oxide in the anionic form. For 2-substituted 3-hydroxypyridine-1-oxides, a satisfactory correlation exists between the chemical shift and theπ-electron density.
