The Radical Addition and Telomerisation of Conjugated Dienes

Reactions are reviewed involving the radical addition and telomerisation of conjugated dienes with halogeno-derivatives of aliphatic hydrocarbons, thiols, sulphonyl chlorides, stannanes, t-butyl hypochlorite, chlorine, and hydrogen bromide. The mechanisms are examined of reactions occurring under the influence of the usual radical-generating initiators, and also of redox systems based on salts of metals of variable valency, peculiarities of the reaction of the growing chain in the allyl radical caused by its low reactivity. A considerable part of the paper deals with problems of the structural and steric isomerism of the addition products, the kinetics of the reactions under consideration, and the reactions of several analogues of conjugated dienes. A list of 86 references is included.
