Can Single-Electron Transfer Break an Aromatic Carbon−Heteroatom Bond in One Step? A Novel Example of Transition between Stepwise and Concerted Mechanisms in the Reduction of Aromatic Iodides
TL;DR: In this paper, the thermodynamic factors governing the competition between the two mechanisms are the standard free energy of anion radical cleavage, ∆GC 0 (eq 1) under these conditions.

Reductive Cleavage of Carbon Tetrachloride in a Polar Solvent. An Example of a Dissociative Electron Transfer with Significant Attractive Interaction between the Caged Product Fragments
TL;DR: In this article, an extension of the theory of dissociative electron transfer is proposed to rationalize the kinetic results and estimate the magnitude of the interaction energy, which explains how a relatively small interaction energy results in a substantial acceleration of the reaction, caused by both an increase of the driving force and a decrease of the intrinsic barrier.

Stepwise and concerted pathways in photoinduced and thermal electron-transfer/bond-breaking reactions. experimental illustration of similarities and contrasts.
TL;DR: Electrochemical and photoinduced reductive cleavages of four compounds, 4-cyano-alpha-trifluorotoluene, are investigated and compared in terms of concerted vs stepwise mechanisms to show a trend of passing from a concerted to a stepwise mechanism when going from the electrochemical to the photochemical conditions.

Stabilities of Ion/Radical Adducts in the Liquid Phase as Derived from the Dependence of Electrochemical Cleavage Reactivities upon Solvent
TL;DR: The existence of significant ion/radical interactions in polar media is confirmed and a route to their determination opened.

Quantum Yields Lower than Unity in Photo‐ induced Dissociative Electron Transfers: The Reductive Cleavage of Carbon Tetrachloride
TL;DR: The photoinduced reductive cleavage of CCl4 provides a clear illustration of the recent theoretical prediction, that photoinduced dissociative electron transfers are not necessarily endowed with a unity quantum yield.
