Separated concerted proton-electron transfer (sCPET) reactions of two series of phenols with pendent substituted pyridyl moieties are described. The pyridine is either attached directly to the phenol (HOAr-pyX) or connected through a methylene linker (HOArCH(2)pyX) (X = 4-NO(2), 5-CF(3), 4-CH(3), and 4-NMe(2)). Electron-donating and -withdrawing substituents have a substantial effect on the chemical environment of the transferring proton, as indicated by IR and (1)H NMR spectra, X-ray… Expand

Analysis of Hydrogen-Bonding Effects on Excited-State Proton-Coupled Electron Transfer from a Series of Phenols to a Re(I) Polypyridyl Complex
In the present study of proton-coupled electron transfer (PCET) reactions, the excited-state of a fac-[(CO)3ReI(bpy)(4,4′-bpy)]+ (bpy = 2,2′-bipyridine and 4,4′-bpy = 4,4′-bipyridine) complex wasExpand
Conformational Change with Steric Interactions Affects the Inner Sphere Component of Concerted Proton-Electron Transfer in a Pyridyl-Appended Radical Cation System.
TLDR
Despite the structural similarity between the compounds, differences in the inner sphere component for CPET affect the kinetics, and kinetic isotope effects support concerted proton–electron transfer (CPET) as the mechanism. Expand
Proton-coupled electron transfer in azobenzene/hydrazobenzene couples with pendant acid-base functions. Hydrogen-bonding and structural effects.
TLDR
Electron transfer in azobenzene derivatives bearing two carboxylic acid groups is coupled with intramolecular proton transfer in a stepwise manner in the title 2e(-) + 2H(+) redox couple to produce a square scheme mechanism in which electron transfer and structural change are not concerted. Expand

Separating Proton and Electron Transfer Effects in Three-Component Concerted Proton-Coupled Electron Transfer Reactions.
TLDR
The results imply a synchronous concerted mechanism, in which the proton and electron transfer components of the CPET process make equal contributions to the rate constants. Expand
Structural and medium effects on the reactions of the cumyloxyl radical with intramolecular hydrogen bonded phenols. The interplay between hydrogen-bonding and acid-base interactions on the hydrogen atom transfer reactivity and selectivity.
TLDR
Results clearly show that in acetonitrile systems the interplay between intramolecular hydrogen bonding and Brønsted and Lewis acid-base interactions can drastically influence both the HAT reactivity and selectivity. Expand
Isolating the Effects of the Proton Tunneling Distance on Proton-Coupled Electron Transfer in a Series of Homologous Tyrosine-Base Model Compounds.
TLDR
Vibrational compression of the tunneling distances, as well as higher vibronic transitions, that contribute to concerted proton coupled electron transfer must also be considered. Expand
Transition State Asymmetry in C-H Bond Cleavage by Proton-Coupled Electron Transfer.
TLDR
The results probe the fundamental rate vs. driving force relationships in this MS-CPET reaction at carbon by separately modulating the driving force for the proton and electron transfer components and suggest that the transition states for these reactions are imbalanced. Expand
Proton-Coupled Electron Transfer in a Series of Ruthenium-Linked Tyrosines with Internal Bases: Evaluation of a Tunneling Model for Experimental Temperature-Dependent Kinetics.
TLDR
A commonly employed theoretical model for proton tunneling which includes a harmonic distribution of proton donor-acceptor distances due to vibrational motions of the molecule is evaluated, and it is found that donor- acceptor compression is more facile in the compounds with shorter PT distance; however, this is contrary to independent calculations for the same compounds.

Multiple-site concerted proton-electron transfer reactions of hydrogen-bonded phenols are nonadiabatic and well described by semiclassical Marcus theory.
TLDR
Results for the oxidation of HOAr-Py, in which the phenol and base are conjugated, and for oxidation of 2,4,6-(t)Bu(3)C(6)H(2)OH, which lacks a base, show that both have substantially lower λ and larger pre-exponential terms, a very clear demonstration that the reactions are nonadiabatic. Expand

Kinetic effects of hydrogen bonds on proton-coupled electron transfer from phenols.
TLDR
The results suggest that while a concerted reaction has a relatively high reorganization energy (lambda), this may be significantly reduced by the hydrogen bonds, allowing for a lower barrier reaction path, which is ideal for PCET reactions in biological systems. Expand

TLDR
These theoretical results qualitatively reproduce the experimental faster reactivity of the reaction of the pyridyl derivative 1 versus the CH(2)-pyridine or amine group, but the computed factor of 5 is smaller than the experimental 10(2). Expand

TLDR
Analysis of PCET in two biomimetic covalently linked Ru(bpy)(3)-tyrosine complexes with the phenolic proton hydrogen-bonded to an internal carboxylate group found, unexpectedly, that the hydrogen bond in SA is in fact weaker than the hydrogen Bond in the complex with PA, which forced us to reassess an earlier hypothesis that the proton coupling term for CEP with SA is increased by a stronger hydrogen bond.
