Electrochemical and Homogeneous Proton-Coupled Electron Transfers:Concerted Pathways in the One-Electron Oxidation of a Phenol Coupled with an Intramolecular Amine-Driven Proton Transfer

摘要

Proton-coupled electron transfers (CPET) currently attract considerable attention in view of their likely involvement in many natural processes.In this connection,ortho-substituted 4,6-di(tert-butyl)phenols in which the phenolic hydrogen atom is H-bonded to the nitrogen atom of a nearby amine are particularly interesting mimics,such as the molecules shown in Scheme 1 and other similar compounds.
