Comments on 'How Single and Bifurcated Hydrogen Bonds Influence Proton-Migration Rate Constants,Redox,and Electronic Properties of Phenoxyl Radicals'

摘要

In a recent communication,Thomas et al.studied the oxidations of three hydrogen-bonded phenols.Such compounds serve as interesting models for hydrogen-bonded tyrosine and tyrosyl radical residues in biological systems.EPR data and DFT calculations provided strong evidence for the nature of the phenoxyl radical products of one-electron oxidation.The cyclic voltammetry (CV) data were simulated and interpreted using a model with initial inter-facial electron transfer and subsequent slow proton transfer.
