Radical addition

from Wikipedia, the free encyclopedia

A radical addition is a reaction mechanism in organic chemistry in which atoms or groups of atoms are added ( added ) to a molecule with a carbon-carbon multiple bond . This chemical reaction is started by radicals and, if not stopped, takes place as a radical chain reaction . The process is analogous to radical substitution .

To start the reaction, so-called initiators are required, with the help of which the first radicals are generated. Peroxides are suitable for this . Instead, light or high temperatures can also initiate the radical addition. The radical addition does not follow the Markovnikov rule , which is why one speaks of anti- Markovnikov products.
