Abstract

Abstract : Developing efficient and recyclable heterogeneous catalysts for organic reactions in water is important for the sustainable development of chemical industry. In this work, Pd nanoparticles supported on DABCO‐functionalized porous organic polymer was successfully prepared through an easy copolymerization and successive immobilization method. Characterization results indicated that the prepared catalyst featured big surface area, hierarchical porous structure, and excellent surface amphiphilicity. We demonstrated the use of this amphiphilic catalyst in two case reactions, i.e. the aqueous hydrodechlorination and Suzuki‐Miyaura coupling reactions. Under mild reaction conditions, the catalyst showed high catalytic activities for the two reactions. In addition, the catalyst could be easily recovered and reused for several times. Also, no obvious Pd leaching and aggregation of Pd nanoparticles occurred up during the consecutive reactions. Abstract : Pdnanoparticle supported on DABCO‐functionalized porous organic polymer was successfully prepared. The obtained catalyst possessed big surface area, hierarchical porous structure, and excellent surface amphiphilicity, these properties enable the solid as efficient catalyst for catalyzing aqueous hydrodechlorination and Suzuki‐Miyaura coupling reactions.
