Catalysis of Radical Reactions: A Radical Chemistry Perspective

Angewandte Chemie - International Edition, 2016
The area of catalysis of radical reactions has recently flourished. Various reaction conditions have been discovered and explained in terms of catalytic cycles. These cycles rarely stand alone as unique paths from substrates to products.

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 ...

Unveiling the Origins of Selective Oxidation in Single-Atom Catalysis via Co-N4-C Intensified Radical and Nonradical Pathways.

Environmental Science and Technology, 2022
Single-atom catalysts (SACs)-based peroxymonosulfate (PMS) systems are highly selective to the type of organic pollutants while the mechanisms remain ambiguous.

Aging: a theory based on free radical and radiation chemistry.

Journal of Gerontology, 1956
The phenomenon of growth, decline and death—aging—has been the source of considerable speculation (1, 8, 10). This cycle seems to be a more or less direct function of the metabolic rate and this in turn depends on the species (animal or plant) on which ...

Commentary: When is a Radical not a Radical?

Free Radical Research, 1996
It is not commonly realised that symmetrical Fe(III) complexes are expected to have EPR spectra dominated by a symmetrical narrow line close to the free-spin g-value. The aim of this note is to stress that such features can be mistakenly identified as the spectra for stable organic radicals.

The free radical theory of aging matures.

Physiological Reviews, 1998
The free radical theory of aging, conceived in 1956, has turned 40 and is rapidly attracting the interest of the mainstream of biological research.

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 ...

Superoxide radical and superoxide dismutases.

Annual Review of Biochemistry, 1995
O2- oxidizes the [4Fe-4S] clusters of dehydratases, such as aconitase, causing-inactivation and release of Fe(II), which may then reduce H2O2 to OH- +OH.. SODs inhibit such HO.
