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

The one-pot synthesis of valuable E -chalcones is achieved using a multifunctional Ru@SiO 2 -[Pd–NHC] catalytic system combining molecular and nanoparticle sites for efficient carbonylative Sonogashira coupling and selective hydrogenation.
