Resumen:
Proton-coupled electron transfer (PCET) reactions are crucial for the optimal functioning of a broad scope of5 chemical and biological processes. In this report, we present an unprecedented type of concerted PCET (cPCET), in which a6 chalcogen atom acts as the electron donor. The nature of this mechanism is key for understanding the reactivity of different radical-7 trapping antioxidants having heavy chalcogens (S, Se, or Te) in their structures. Moreover, this chalcogen-assisted cPCET is likely to8 be occurring in multiple systems of biological interest.
