“…The best choice of such a support is an insoluble lightly cross-linked polymer resin. Many research groups have proved the success of solid phase synthesis of dendrimers on polymer supports (14)(15)(16)(17). Catalysts derived from the dendrimers supported on insoluble supports were shown to be highly efficient and reusable (18)(19)(20)(21).…”

Ⅺ Poly(amidoamine) dendrimers were synthesized on cross-linked aminomethyl polystyrene. Palladium complexes of supported dendrimers prepared by ligand exchange method were reduced to dendrimernanoparticle conjugates supported on polystyrene resin. The supported nanoparticles were used as heterogeneous catalysts for the Suzuki coupling between aryl boronic acids and aryl halides. Various factors affecting the catalysts performance were studied. Higher generation dendrimers gave well-defined nanoparticles without agglomeration and these particles showed good catalytic performance.

“…1-5 Several fabrication approaches for supported PdNPs have been reported. [6][7][8][9][10][11][12][13] In addition, preparation of these materials that can also be easily recycled have been reported. However, some of the supported PdNPs still result in Pd leaching, 10,11,[14][15][16][17] and this needs to be solved in a rapid manner.…”

The effects of the ligand used for fabricating palladium (Pd)-incorporated porous polymer composites on their catalytic performances were examined from the perspective of catalysis sustainability. To perform this research, poly(amidoamine) (PAMAM) dendrimers, which were generation zero (G0) and higher, up to G6, the breakdown structure of G0 (that is, the half (G0h) and quarter (G0q)) and a typical small molecule (that is, N,N-dimethyl ethylenediamine (DMEn)) were utilized as ligands. The catalytic performances of the polymer composites were investigated using the aqueous Suzuki-Miyaura carbon crosscoupling reaction as a model reaction. Concerning the efficiency, recyclability and Pd-leaching behavior of the catalytic reaction, polymer composites that were fabricated with PAMAM dendrimers (that is, G1 and higher generations) proved to possess the potential for application as sustainable heterogeneous catalysts.
