Aryl radical
An Aryl radical in organic chemistry is an reactive intermediate and an arene compound incorporating one free radical carbon atom as part of the ring structure. As such it is the radical counterpart of the Arenium ion. The parent compound is the phenyl radical C6H5..〔''Minireview Intermolecular Olefin Functionalisation Involving Aryl Radicals Generated from Arenediazonium Salts'' Markus R. Heinrich Chemistry - A European Journal 2008 Volume 15 Issue 4, Pages 820 - 833〕 Aryl radicals are intermediates in certain organic reactions.
==Synthesis==
Aryl radicals can be obtained via aryl diazonium salts. Alternatives for these salts are certain aryl triazenes and aryl hydrazines. Aryl bromides and iodides can be converted to aryl radicals via tributyltin hydride and related compounds and silyl hydrides. Aryl halides can also be converted via electrochemical cathodic reduction
The mushroom ''Stephanospora caroticolor'' is suspected to generate an aryl radical as part of its biological chemical defence mechanism.
