Reduction of carbon dioxide to high value targets including hydrocarbons and alcohols, carbon monoxide, and formic acid remains a critical need to mitigate the atmospheric CO2 levels. Systems competent for C–C bond formation from CO2 are particularly attractive as these provide a route towards carbon neutral fuels and other commodity chemicals. Molecular systems competent for this reactive are few, and most operate at strongly reducing potentials and suffer from slow reaction kinetics. Here we will describe a di(μ-sulfido)diiron cyclophane complex which effects catalytic CO2 oxalate conversion using excess reductants and under an applied potential. Mechanistic studies on this system and comparison to other reported systems will be presented.
