Abstract
Silver salts or complexes promote a variety of useful C—C bond-forming transformations in organic synthesis, usually under very mild conditions. In these reactions, silver can be engaged either as catalyst or cocatalyst, or as an organometallic reagent. Organosilver species act as mild nucleophiles toward alkyl halides or epoxides, but also toward carbonyl and imine derivatives and related heterocycles such as pyridines or quinolines. Silver can promote the homocoupling of a variety of organometallic reagents, of heterocycles, and of electron-deficient alkenes upon addition of the corresponding fluoride salts. Silver also promotes the cross coupling of alkyl or aryl halides, alkenes and alkynes, and even (het)arenes. Furthermore, silver salts often improve the efficiency of palladium-catalyzed cross-coupling reactions, or coupling reactions involving C—H activation or decarboxylation.
