by polyvinyl alcohol as a highly active, durable and reusable catalyst
A novel catalyst is synthesized based on the immobilization of palladium on γ-Fe2O3@SiO2–(CH2)3–PDTC nanoparticles and is used as a highly active catalyst for the Heck/Sonogashira coupling reactions.
A novel Cu3L2 metal–organic cage, which features coordination interaction triggered solubility, can be a highly active and reusable catalyst to homogeneously catalyse the one-pot aldehyde–alkyne–amine A3-coupling reaction.
Highly monodispersed palladium nanoparticles supported on polymer containing phosphorus and nitrogen ligands was successfully synthesized, characterized and used in Suzuki and Sonogashira coupling reactions in water.
A highly active and reusable catalyst Pd@PNP was developed for Suzuki–Miyaura reaction of aryl chlorides and bromides with aryl boronic acids, and the corresponding biphenyl compounds were obtained in good to excellent yields.
