Organocobalt(III) complexes (R-Co), defined as cobalt complexes featuring a carbon-cobalt bond, are largely used to produce carbon-centered radicals by homolytic cleavage of their C-Co bond under mild conditions. They are key compounds in cutting-edge developments in the fields of organic chemistry, biochemistry, medical research, radical reactions, and organometallic chemistry. This is the first Review of the use of R-Co in both organic and polymer chemistries. Although pioneering works in organic synthesis have largely contributed to the implementation of R-Co in polymer design, the two fields have evolved independently, with many breakthroughs on both sides. The main motivation of this Review is to confront both fields to stimulate cross-fertilization. It notably describes the most important synthetic pathways for R-Co, the influence of the ligand structure and the environment of the complex on the C-Co bond strength, the modes of formation of the radicals, and the most relevant R-Co-promoted radical reactions, with a focus on the main reaction mechanisms.

Recently, long-lived, organic radical species have attracted much attention from chemists and material scientists because of their unique electronic properties derived from their magnetic spin and sin...
Coal exposed to an air atmosphere absorbs the atmospheric oxygen; this involves physical adsorption and chemisorption to form surface oxides (including hydro-peroxides). These weathering processes, wh...
Magnetic biochar (MBC) has been used to remove hexavalent chromium (Cr(VI)) from water, but the roles of FeO and persistent free radicals (PFRs) in MBC in Cr(VI) removal are still less investigated. I...
This review presents data showing the possibility of novel pathways to be realized for free-radical transformations of glycerophospholipids and sphingolipids. These transformations include the stages ...
Many catchment management schemes in the UK have focussed on peatland restoration to improve ecosystem services such as carbon sequestration, water quality and biodiversity. The effect of these scheme...
The purpose of this study is to evaluate the efficacy of 3 different rapamycin-eluting-stent platforms to reduce coronary artery reblockage after stent implantation
The study aims to evaluate the hypothesized benefits of a systematic organic diet for children, over those of a conventional diet. The specific objectives of this study are to: i) Demonstr...
This study will examine the relationship between free radicals in the saliva and periodontitis. 30 adults, 15 with periodontitis and 15 as a control group will give a sample of saliva befo...

The aim of this prospective, randomized study is to compare the efficacy and safety of biodegradable polymer based limus-eluting stents (BPDES) with permanent polymer based everolimus elut...
Organic compounds containing both the hydroxyl and carboxyl radicals.
The major metabolite in neutrophil polymorphonuclear leukocytes. It stimulates polymorphonuclear cell function (degranulation, formation of oxygen-centered free radicals, arachidonic acid release, and metabolism). (From Dictionary of Prostaglandins and Related Compounds, 1990)
A broad class of substances containing carbon and its derivatives. Many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements. They exist in either carbon chain or carbon ring form.
Multisubunit enzyme complexes that synthesize ADENOSINE TRIPHOSPHATE from energy sources such as ions traveling through channels.
A family of anaerobic METHANOCOCCALES whose organisms are thermophilic methanogens that produce methane from hydrogen and simple carbon sources such as carbon dioxide.
