Tuning radical reactivity for selective radical/radical cross-coupling
Science Bulletin, 2018Radical/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 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.

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.

Nanotechnology has made significant advances in the reduction of free radical damage in the field of materials science. Cross-disciplinary interactions and the application of this technology to biological systems has led to the elucidation of novel nanoparticle antioxidants, which are the subject of this review. Recent reports suggest that cerium oxide

Generation and Radical–Radical Cross-Coupling of Alkenyloxy Radical
Organic LettersAlkene-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.

The search for new radicals goes on. Recently R. L. Snider ([6], see page 216) introduced the following notion. Let α and β be any two radicals. A ring R will be said to be an (α : β) ring if for any ideal A of R, we have α (R/A) ≧ β (R/A).

The radical hysterectomy is the standard approach for the treatment of women with early cervical cancer. However, it has increasingly been recognized that a more individualized approach to treatment should be taken. In particular, careful pretreatment evaluation should reduce the number of women receiving adjuvant radiotherapy.

This book is a collection of essays that study the diffusion of radical ideas in Britain from the period of the English Revolution in the mid-seventeenth century to the Romantic Revolution in the early nineteenth century. It explores the modes of articulation and dissemination of radical ideas in the period by focusing on actors (“radical voices”) and ...
