Description
Summary:Photoredox catalysis (PRC) and synthetic organic electrochemistry (SOE) are often considered competing technologies in organic synthesis. Their fusion has been largely overlooked. We review state‐of‐the‐art synthetic organic photoelectrochemistry, grouping examples into three categories: 1) electrochemically mediated photoredox catalysis (e‐PRC), 2) decoupled photoelectrochemistry (dPEC), and 3) interfacial photoelectrochemistry (iPEC). Such synergies prove beneficial not only for synthetic “greenness” and chemical selectivity, but also in the accumulation of energy for accessing super‐oxidizing or ‐reducing single electron transfer (SET) agents. Opportunities and challenges in this emerging and exciting field are discussed. Photochemistry with potential: The synergy of photochemistry and electrochemistry in organic synthesis is beneficial not only for synthetic sustainability and chemical selectivity, but also in the accumulation of energy for accessing super‐oxidizing or ‐reducing single electron transfer agents. Examples of synthetic organic photoelectrochemistry are dissected into three categories: electrochemically mediated photoredox catalysis, decoupled photoelectrochemistry, and interfacial photoelectrochemistry.
