The present invention relates to a method of producing a heterogeneous catalyst suitable for catalyzing Heck, Suzuki-Miyaura Sonogashira coupling and 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 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) salt; d) suspending said carrier in an organic solvent thereby obtaining a suspension; 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.
本发明涉及一种生产适用于催化Heck、Suzuki-Miyaura Sonogashira偶联和Buchwald-Hartwig反应的杂多相催化剂的方法,包括以下步骤:a)提供一种大孔载体,所述大孔载体由核心和多个离子交换基团共价键合到所述核心表面组成,其中至少90%的离子结合到所述载体上是
甲酸根离子;b)在极性溶剂中使载体膨胀;c)提供
钯(II)盐;d)将所述载体悬浮在有机溶剂中,从而得到一种悬浮液;e)将所述
钯盐加入所述悬浮液中,并在0-70℃的温度范围内使所得混合物反应,直至所述载体变黑;f)在
水中清洗所述载体;g)在真空下干燥所述载体。
