Elektronentransfer und Ionenpaar-Bildung, 20. Zweistufen-Reduktion von Tetra(2′-pyridyl)pyrazin unter aprotischen Bedingungen sowie in Lösungen mit Li⊕- und Na⊕-Leitsalzkationen
Electron transfer and ion pairing, 20. Two-step reduction of tetra(2′-pyridyl)pyrazine under aprotic conditions as well as in solutions containing Li⊕ and Na⊕ conducting salt cations
- Cyclovoltammetric measurements of solutions containing the rather basic tetra-(2′-pyridyl)pyrazine allow to detect even traces of water and thus can be used as a touchstone for aprotic (cH⊕ < 1 ppm) conditions. On exchange of the “innocent” tetrabutylammonium R4N⊕ as supporting electrolyte cation by “interactive” ones such as Li⊕) or Na⊕, considerable changes in the reduction potentials are observed due to ion pair formation.
