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 ...

On the Design of Radical–Radical Cocrystals

Angewandte Chemie, 2018
AbstractFormation of radical–radical cocrystals is an important step towards the design of organic ferrimagnets. We describe a simple approach to generate radical–radical cocrystals through the identification and implementation of well‐defined supramolecular synthons which favor cocrystallization over phase separation. In the current paper we implement

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).

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 ...

Generation and Radical–Radical Cross-Coupling of Alkenyloxy Radical

Organic Letters
Alkene-attached oxygen radicals are rarely used, as highly reactive oxygen radicals are incompatible with the alkene moiety. The direct radical-radical cross-coupling of O radicals is also challenging (limited to N-O bond formation) because of the lack of suitable persistent radical species.

Radical Fashion and Radical Fashion Innovation

Journal of Global Fashion Marketing, 2010
This is a study of the related concepts of radical fashion and radical fashion innovation. Radical fashions are defined here as those that may never enter the market at all, and exist primarily on runway shows, in exhibitions and in publicity; by contrast, radical fashion innovations may be very successful in the marketplace. Radical fashions represent

Radical and Radical–Ionic Multicomponent Processes

Chemistry – A European Journal, 2009
AbstractAll in one pot! Radical, radical–ionic, and radical–organometallic MCR are highly convergent processes, representing a useful pathway to molecular and structural diversity (see scheme). This concept article highlights recent developments in the field and shows the potential of the strategy for the economical elaboration of various kinds of ...

Dioxin Formations from the Radical/Radical Cross-Condensation of Phenoxy Radicals with 2-Chlorophenoxy Radicals and 2,4,6-Trichlorophenoxy Radicals

Environmental Science & Technology, 2010
It is important to understand the role of phenol in the dioxin formations because it is present in the high amount in municipal waste incinerators (MWIs). The formation mechanism of dioxins from the cross-condensation of PhRs with 2-CPRs and 2,4,6-TCPRs was investigated by using hybrid density functional theory (DFT) and compared with the dioxin ...

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.

Are anion radicals unable to undergo radical-radical dimerization?

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1982
It has recently been shown that S-cyanoanthracene (ANCN) can be formed upon electrochemically induced [la] SRNl nucleophilic substitution [lb] of 9-halo-anthracenes in DMSO [lc] . Since the radical anions of ANCN may play an important role in the propagation and termination steps of the electrocatalytic process, the question was raised of the possible ...
