Electrochemistry The electrochemical redox properties of the newly synthesized Fc-DTFs 9 and 12, the 1,1′-bis(1,3-DTF)Fc’s 8, 10, 11, and the acylferrocenes

• . Their electrochemistry was studied and compared to the previously reported derivative 9. In CH2Cl2 on a Pt electrode and at ambient temperature, compound 12 showed two oxidation waves associated with two reduction waves with peak potentials of 698, 1158 mV at scan rates 100 mV s−1. In contrast the
