The Impact of a Proton Relay in Binuclear α-Diimine-Mn(CO)3 Complexes on the CO2 Reduction Catalysis

Abstract: Herein, we describe the redox chemistry of bi- and mononuclear α-diimine-Mn­(CO)3 complexes with an internal proton source in close proximity to the metal centers and their catalytic activity in the electrochemically driven CO2 reduction reactions. In order to address the impact of the two metal sites and of the proton source, we investigate a binuclear complex with phenol moiety, 1, a binuclear Mn complex with methoxyphenol unit instead, 2, and the mononuclear analogue with a phenol unit, 3.

“…IR spectroelectrochemical experiments (IR‐SEC) were conducted to get structural information on the in situ formed reduced Mn(CO) 3 species during catalysis (Figure 3). [26] The redox chemistry of 1 in DMF has been investigated in detail previously by various methods, and the species formed in THF upon reduction are essentially the same (Figure S46) [14] . Initial reduction of 1 in the absence of any substrate leads to the formation of A (blue trace).…”

“…B exhibits a characteristic CO vibration at a frequency of 1982 cm −1 . The shift of the A ’ CO vibrational mode of B with regard to the one of 1 is characteristic for a 1 ē reduction at each α‐diimine unit and a five‐coordinated metal centre [14, 28] . Thus, B has been assigned previously to [Mn 2 (H −1 L)(CO) 6 ] − [14] .…”
