A radical approach to radicals

Acta Crystallographica Section D Structural Biology, 2022
Nitroxide radicals are characterized by a long-lived spin-unpaired electronic ground state and are strongly sensitive to their chemical surroundings. Combined with electron paramagnetic resonance spectroscopy, these electronic features have led to the widespread application of nitroxide derivatives as spin labels for use in studying protein structure ...

Perchlorophenalenyl Radical

Journal of the American Chemical Society, 2001
We report the preparation and solid-state characterization of the perchlorophenalenyl radical (1). The radical is initially obtained as a yellow-green solid by reduction of the perchlorophenalenium salt (12(+)). This solid sublimes in a sealed tube to give black shiny hexagonal crystals of the perchlorophenalenyl radical (1).

Terrorism, radicalization and de-radicalization

Current Opinion in Psychology, 2016
In this article, we review the literature and present a model of radicalization and de-radicalization. In this model, we distinguish three phases in radicalization: (1) a sensitivity phase, (2) a group membership phase and (3) an action phase. We describe the micro-level, meso-level and macro-level factors that influence the radicalization process in ...

Tuning radical reactivity for selective radical/radical cross-coupling

Science Bulletin, 2018
Radical/radical cross-coupling represents a straightforward way for the construction of new chemical bonds in theory and has received more and more attention over the past several years. Until now, it is challenging to achieve the selective bond formation between two transient radicals since selective radical cross-coupling usually happens between ...

Roaming Radicals

Annual Review of Physical Chemistry, 2011
Roaming is a recently verified unusual pathway to molecular products from unimolecular dissociation of an energized molecule. Here we present the evidence for this pathway for H2CO and CH3CHO. Theoretical analysis shows that this path visits the plateau region of the potential energy surface near dissociation to radical products.

RADICAL-RADICAL REACTIONS

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.
