Radical elimination can be viewed as the reverse of radical addition. In radical elimination, an unstable radical compound breaks down into a spin-paired molecule and a new radical compound. Shown below is an example of a radical elimination reaction, where a benzoyloxy radical breaks down into a phenyl radical and a carbon dioxide molecule. [7]

In chemistry, radical initiators are substances that can produce radical species under mild conditions and promote radical reactions. [1] These substances generally possess weak bonds—bonds that have small bond dissociation energies. Radical initiators are utilized in industrial processes such as polymer synthesis.
In chemistry and biology, reactive oxygen species (ROS) are highly reactive chemicals formed from diatomic oxygen (O 2), water, and hydrogen peroxide. Some prominent ROS are hydroperoxide (O 2 H), superoxide (O 2 − ), [ 1 ] hydroxyl radical (OH .
In organic chemistry, a radical anion is a free radical species [1] that carries a negative charge. Radical anions are encountered in organic chemistry as reduced derivatives of polycyclic aromatic compounds, e.g. sodium naphthenide. An example of a non-carbon radical anion is the superoxide anion, formed by transfer of one electron to an ...
Most notably hydroxyl radicals are produced from the decomposition of hydroperoxides (ROOH) or, in atmospheric chemistry, by the reaction of excited atomic oxygen with water. It is also an important radical formed in radiation chemistry, since it leads to the formation of hydrogen peroxide and oxygen , which can enhance corrosion and stress ...

Another example is Kolbe electrolysis. Radical-nucleophilic aromatic substitution is a special case of nucleophilic aromatic substitution. Carbon–carbon coupling reactions, for example manganese-mediated coupling reactions. Elimination reactions; Free radicals can be formed by photochemical reaction and thermal fission reaction or by ...
