The synthesis, structures, and electrochemistry of 1′-heteroaryl-2,5-dimethylazaferrocenes

We report the synthesis of 1′-heteroaryl-2,5-dimethylazaferrocenes (heteroaryl = 2-bromothiophen-5-yl and 2-bromopyrid-6-yl) via palladium catalysed cross-coupling reactions along with their crystallographically determined structures. The newly synthesized compounds as well as the parent 2,5-dimethylazaferrocene have been investigated by cyclic voltammetry (CV) and were found to exhibit reversible first oxidations followed by an irreversible oxidation at considerably higher potential.

A synthetic route to 1′-heteroaryl substituted 2,5-dimethylazaferrocene derivatives is reported along with their crystallographical and electrochemical characterization.Figure optionsDownload as PowerPoint slide
