Abstract
Palladium 15−20 nm particles stabilized by a Keggin-type polyoxometalate were prepared by reduction of K5PPdW11O39 with H2. The nanoparticles were shown to be effective catalysts for Suzuki-, Heck-, and Stille-type carbon−carbon coupling and carbon−nitrogen coupling reactions of bromoarenes in aqueous media. Chloroarenes were also reactive in reaction media without solvent.Keywords
