Fluorous phase soluble palladium nanoparticles as recoverable catalysts for Suzuki cross-coupling and Heck reactions

1,5-Bis(4,4'-bis(perfluorooctyl)phenyl)-1,4-pentadien-3-one stabilizes palladium(0) nanoparticles (transmission electron microscopy) formed in the reduction of palladium dichloride with methanol. These palladium colloids are soluble in-perfluorinated solvents, and they are efficient recoverable catalysts for Suzuki cross-couplings and Heck reactions under fluorous biphasic conditions.
