Polyoxometalates: Synthesis and Applications

Phosphonium salts were synthesized and used as support for palladium nanoparticles. It was demonstrated that the catalytic behavior of palladium nanoparticles in Suzuki cross-coupling reaction is determined by the ratio of the phosphonium ionic liquid to palladium source and the nature of the stabilizer. Transition electron microscopy and dynamic light scattering techniques allowed to determine the most effective range of stabilizer concentration in the reaction media.
