Recent Advances in the Chemistry of Compounds Containing S-SI Moieties
The majority of radical reactions of interest to synthetic chemistry are chain processes in which radicals are generated by some initiation process, and which then undergo a series of propagation steps generating fresh radicals and finally disappear by combination or disproportionation. A synthetically useful radical chain reaction should require as little radical initiator as possible and should form few side products.1 This is possible only if the chain propagating radical meets certain conditions of reactivity and selectivity; that is (i) the selectivities of the radical involved in the chain must differ from one other and (ii) the reaction between radicals and non radicals must be faster than radical combination reactions.
