However, that changed in , when Russian chemist Moses Gomberg first synthesized the carbon radical triphenylmethyl. Nowadays, we know that organic free radicals have tremendous biological and synthetic significance.

Key to the chemistry of organic radicals is their structure. The carbon atom, with its single unpaired electron, is desperate to bond with another atom to obtain its full complement of electrons. As a result, free radicals are extremely reactive and have been implicated in a wide range of biological processes including aging and cancer development. Indeed, our growing knowledge of organic free radicals has helped us to understand many natural phenomena, from DNA synthesis to sunburn.

Organic free radicals also play many vital roles in industry, as they are instrumental in producing various materials such as plastics and synthetic rubber.

Our first named reaction featuring free radicals is the Hunsdiecker reaction , which describes the process by which silver salts of carboxylic acids react with a halogen to produce an alkyl halide with one fewer carbon atom. Originally, the silver salts used in this reaction were prepared by treating various carboxylic acids with silver oxide. Fortunately, a range of strategies have been developed to overcome this problem — for example, using acid chlorides as a more reactive functional group, or using thallium I carboxylates in place of silver.

Another derivation of the Hunsdiecker reaction, the Barton modification, has proved very synthetically useful as it is compatible with almost all functional groups. The same year that the Hunsdieckers were producing their alkyl halides, German chemist Hans Meerwein and colleagues conducted a series of experiments to study the reaction of diazo compounds with alpha, beta-unsaturated carbonyl compounds.

Following their pioneering work, the arylation of substituted alkenes with aryldiazonium halides in the presence of a metal catalyst has come to be known as the Meerwein arylation. In the Meerwein arylation, the aryldiazonium halide reagents are usually prepared through the diazotization of the aromatic amines using sodium nitrite and aqueous hydrohalic acids. Once prepared, the halides are reacted immediately with the alkenes in an organic solvent such as acetone or acetonitrile.

This versatile reaction has proved useful in several successful synthesis campaigns and was instrumental in preparing a series of peptide mimetic aldehyde inhibitors of calpain, compounds with a diverse range of therapeutic uses. Discovered over three decades after the Hunsdiecker and Meerwein reactions, the Keck radical allylation describes the coupling of an alkyl halide with allyltributyltin under radical conditions to insert an allyl group. Keck determined that the reaction was generally for primary, secondary and tertiary alkyl bromides, and identified azobisisobutyronitrile AIBN as the most efficient catalyst to initiate the process.
