[Betaines of quaternary salts of pyridine-2-and -4-aldoxim (author's transl)].

The monobetaine derived from the AChE-ractivator bis-[4-hydroxyiminomethyl-pyridinium-(1)-methyl]-either dichloride (obidoxim; Toxogonin), was shown to be in solution an intramolecular CT-complex. Some betaines of quaternary salts of pyridine-aldoximes were isolated.
