Systems containing ferrocene triazole derivatives are of high interest today, because they have potential applications in various fields of electrochemical detection, sensing and host-guest chemistry.[1-3] The combination of ferrocene units with N-heterocyclic carbenes can be used for the generation of metal complexes which can be used for the investigation of redox properties and redox-switchable catalysis.[4,5] Therefore, we synthesised different monosubstituted ferrocene triazoles starting from azidoferrocene and terminal alkynes. Furthermore, the methylation of these compounds led to the formation of triazolium salts which are the precursor compounds for the generation of carbene complexes. We obtained heterobimetallic triazole and triazolylidene complexes according to literature procedures.[6-8] These compounds were characterised and (spectro-)electrochemically investigated.
