Reaction mechanisms: radical and radical ion reactions
Annual Reports Section "B" (Organic Chemistry), 2013Radical reactions endear themselves to organic chemists due to their ability to mediate otherwise difficult transformations (e.g. functionalization of unactivated hydrocarbons), and the associated challenges with predicting and/or controlling their reactivity.

Annual Review of Physical Chemistry, 1996
▪ Abstract  Radical-radical reactions generally proceed on potential energy surfaces that have no maximum. Collisional deactivation leads to a stable molecular product; alternatively, radical or molecular products can be formed via dissociation channels additional to those regenerating the reactants.

Formation of Radicals in the Mitsunobu Reaction
The Journal of Organic Chemistry, 1995The first step of the Mitsunobu reaction, involving the reaction of triphenylphosphine with diisopropyl (or diethyl) azodicarboxylate, results in the formation of a radical cation. The EPR spectra of the N-centered radicals reveal hyperfine coupling to two nitrogen nuclei, a phosphorus nucleus, and one or two protons from the alkyl CH (or CH2) groups ...

A free-radical reaction is a chemical process in which molecules having unpaired electrons are involved. The radical species could be a starting compound or a product, but in organic chemistry, the most common cases are reactions that involve radicals as intermediates.

Reaction mechanisms: radical and radical ion reactions
Annual Reports Section "B" (Organic Chemistry), 2011Radicals and radical ions are involved as intermediates in numerous chemical processes that range from synthesis to reactions in biological systems. Knowledge of the mechanisms by which these different reactions proceed is therefore not only of fundamental importance for the development of new synthetic procedures, but is also crucial for the ...

Radicals in enzymatic reactions
Current Opinion in Chemical Biology, 1997Spectroscopic and kinetic evidence for substrate-based radicals in the reactions of lysine 2,3-aminomutase and methane monooxygenase has recently been gathered. Evidence for a protein-based thiyl radical in the mechanism of the action of ribonucleotide reductase has been correlated with the proposed mechanism involving substrate-based radicals ...

Abstract While the catholics had been developing a sustained and well organized drive for relief, the Irish radicals had been both encouraging the catholics and strenuously striving to promote what they regarded as the more comprehensive cause of reform.
