The interaction of carbon-centered radicals with copper(I) and copper(II) complexes

Although alkylcopper(I) reagents are widespread, compounds containing alkyl ligands on Cu II or Cu III are much less common. Such complexes, however, are generated as transient species when carbon-center radicals add to Cu I or Cu II complexes, respectively, and appear to be involved in several copp...

Summary:Although alkylcopper(I) reagents are widespread, compounds containing alkyl ligands on Cu II or Cu III are much less common. Such complexes, however, are generated as transient species when carbon-center radicals add to Cu I or Cu II complexes, respectively, and appear to be involved in several copper-catalyzed organic transformations. A few organocopper(II) and organocopper(III) complexes were found sufficiently robust to allow isolation and full characterization. This article reviews the reactivity of carbon-centered radicals with Cu I and Cu II ions, both in aqueous and non-aqueous environments, with focus on the importance of the resulting organocopper species on atom transfer radical polymerization and on copper-catalyzed radical termination.
