BETAINES FROM NEW HETEROCYCLIC PHENOLS: 9-OXIDO-PYRIDOPYRIMIDIN-5-IUM AND DERIVATIVES.

9-Oxido-pyridopyrimidin-5-ium and its 2,4-dimethyl derivative were obtained from the corresponding hydroxy compounds by ion exchange on Amberlite IRA 401 S.

SYNTHESIS, ELECTRONIC STRUCTURE, AND ABSORPTION SPECTRA OF 9-HYDROXYPYRIDOPYRIMIDINIUM DERIVATIVES

Pyridopyrimidinium salt derivatives have been prepared by condensation of 2-aminopyridinium salts with β-dicarbonyl compounds.The acid-base equilibrium dissociation constants for 2,4-dimethyl-9-hydroxypyridopyrimidinium perchlorate have been measured, and the spectroscopic characteristics of its neutral, anionic, and cationic forms have been determined; the electronic absorption spectra of the neutral and anionic forms of 2,4-dimethyl-9-hydroxypyridopyrimidinium perchlorate have been interpreted based on this experimental and calculated data.
