Palladium nanoparticles stabilized by metal-carbon covalent bond: An efficient and reusable nanocatalyst in cross-coupling reactions

Palladium nanoparticles stabilized by PdC(binaphthyl) covalent bonds have been designed and synthesized. This new class of Pd nanoparticles was efficiently used as reusable catalysts for CC bond forming Heck, Suzuki-Miyaura and Sonogashira cross coupling reactions with high turnover. Even after the several catalytic cycles the Pd NPs had the same reactivity and particle size without any apparent agglomerization. © 2013 Elsevier B.V.
