Jones'n for electrons : Various Rh complexes (see general structure) were formed with diaminocarbenes that contain 1,1′‐disubstituted ferrocenes in their backbones. Electronic communication between the Fe centers in the redox‐active carbenes and the coordinated transition metals was observed. For example, the oxidation potential of the Fe center in a bimetallic complex was found to depend on the electron density of the ligated Rh atom.
