網頁Thermodynamic stability of the dimerization products of unsubstituted phenoxyl radicals according to data from quantum-chemical calculations determined by the MNDO method. … 網頁2024年9月21日 · Alkoxy radicals have long been recognized as powerful synthetic intermediates with well-established reactivity patterns. Due to the high bond dissociation free energy of aliphatic alcohol O–H bonds, these radicals are difficult to access through direct homolysis, and conventional methods have instead relied

Mechanistic study of the dimerization of phenoxyl radicals
網頁The sulfur–sulfur bond in elemental sulfur is homolytically cleaved and the resulting sulfur radicals add to the double-bond initiating polymerization. Interestingly, the polymers are stable, unlike polymeric sulfur, which is a diradical and readily undergoes depolymerization at room temperature to S 8 by “backbiting”. 網頁Radicals from the flavonoids quercetin, (+)-catechin, (+/-)-taxifolin and luteolin, and from all-rac-alpha-tocopherol have been generated electrochemically by one-electron oxidation in deaerated dimethylformamide (DMF), and characterised by electron spin resonance spectroscopy (ESR) after spin-trapp … 網頁Semantic Scholar extracted view of "A stable phenoxy radical inert to oxygen" by G.
