Multi-Step Redox Systems, LVII. - Quaternary Salts of Pyridyl-Substituted 1,3,5-Triazines - A New Class of Two- to Four-Step Reversible Redox Systems.

Gries, Willi-Kurt,Guenther, Erhard,Huenig, Siegfried

, p. 1021 - 1028 (2007/10/02)

The synthesis of 1,3,5-triazines 3-5 a-e substituted by one to three 4-pyridinium rings is described.According to voltammetric data 3-5 constitute a new type of redox systems with reversible electron transfer in two to four separate steps.Reduction by zinc or sodium amalgam in acetonitrile prodces coloured stable solutions of radicals (SEM).
