Optimized Stille Coupling Reactions Catalyzed by Palladium on Carbon with CuI as Cocatalyst.

Abstract The coupling reaction of aryl and vinyl iodides, bromides, and triflates with organostannanes can be effectively conducted using palladium on carbon as a source of Pd0. The yield and rate of reaction are significantly affected by the addition of copper iodide as co-catalyst and triphenylarsine as ligand.
