One-pot synthesis of <i>E</i>-chalcones using a multifunctional catalyst comprised of ruthenium nanoparticles and palladium N-heterocyclic carbene complexes immobilized on silica.

ABSTRACT: The integrated one-pot synthesis of valuable E-chalcones from aryl iodides, phenylacetylenes, CO and H₂ is achieved using a single catalyst material. The multifunctional catalytic system is composed of a silica support on which ruthenium nanoparticles and covalently functionalized palladium N-heterocyclic carbene (NHC) complexes are jointly assembled. The resulting Ru@SiO₂-[Pd-NHC] catalyst was characterized by a variety of techniques including N₂ physisorption, solid-state nuclear magnetic resonance, electron microscopy, and X-ray photoelectron spectroscopy to collect information on its textural, structural, morphological, and electronic properties. Ru@SiO₂-[Pd-NHC] was found to be active and selective for the one-pot synthesis of a wide
