PROCESS FOR THE PRODUCTION OF PALLADIUM SUPPORTED CATALYSTS FOR CATALYZING HECK, SUZUKI-MIYAURA SONOGASHIRA COUPLING AND BUCHWALD-HARTWIG REACTIONS

摘要

The present invention relates to amethod of producing a heterogeneous catalyst suitable for catalyzing Heck, Suzuki-MiyauraSongashira couplingand Buchwald-Hartwig reactions, comprising the steps of: a) providing a macroporous carrier, said macroporous carrier consisting of a core and a plurality of ion exchange groups covalently of ion exchange groups covalently bonded to the surface of said core, where at least 90% of the ions bound to said carrier are formate ions; b) swelling said carrier in a polar solvent; c) providing a palladium (II) sa d) suspending said carrier in an organic solvent thereby obtaining asuspension; e) adding said palladium salt to said suspension and allowing the resulting mixture to react at a temperature within the range of 0 70 °C until said carrier has turned black; f) washing said carrier in water; g) drying said carrier under vacuum.
