Zusammenfassung

We report on the synthesis of complexes having two equivalent redox active 2,5-dimethylazaferrocenyl entities connected by heteroaryl (heteroaryl = thiophenyl, bithiophenyl and pyridyl) bridges. The new compounds have been investigated by various electrochemical techniques including cyclic voltammetry (CV), differential pulse voltammetry (DPV) and square wave voltammetry (SW) and were found to exhibit two consecutive reversible or partially reversible one-electron oxidations. Comproportionation constants (Kc) calculated from ΔE1/2 values indicate that the thermodynamic stability of their monoxidized forms exceeds those of analogous ferrocenes. In this paper we also report the X-ray crystal structure and UV–Vis spectroelectrochemistry of parent 2,5-dimethylazaferrocene.
