“…Several studies have supported palladium nanocatalyst for cross-coupling reactions [ 27 , 28 ]. For example, in recent years, different types of nanoparticle support materials were investigated; for example, metal oxides [ 29 , 30 , 31 ], zeolites [ 32 , 33 , 34 ], carbons [ 35 , 36 , 37 ], ordered porous materials [ 38 , 39 ] and synthesized polymers [ 40 ] (e.g., ionic polymers [ 41 ]) and modified natural polymers [ 42 , 43 ]. There are several studies on mixed composition for palladium nanoparticle (PdNP) support [ 44 , 45 , 46 , 47 ], and the need for a rational design of catalyst support has been emphasized [ 48 , 49 ].…”

A new family of sterically hindered alkyl(tri-tert-butyl) phosphonium salts (n-CnH2n+1 with n = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20) was synthesized and evaluated as stabilizers for the formation of palladium nanoparticles (PdNPs), and the prepared PdNPs, stabilized by a series of phosphonium salts, were applied as catalysts of the Suzuki cross-coupling reaction. All investigated phosphonium salts were found to be excellent stabilizers of metal nanoparticles of small catalytically active size with a narrow size distribution. In addition, palladium nanoparticles exhibited exceptional stability: the presence of phosphonium salts prevented agglomeration and precipitation during the catalytic reaction.

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.

A novel polymer supported [poly (styrene‐co‐maleic imide) (SMI)]Cu(I) nano‐particles was prepared via in situ reaction of 4‐amino‐5‐methyl‐4H‐1,2,4‐triazole‐3‐thione with [poly (styrene‐co‐maleic anhydride)] (SMA) along with immobilization of CuI. These nano‐particles were fully characterized by using scanning electron microscopy (SEM), energy dispersive spectroscopy analysis, Xray (EDAX), inductively coupled plasma (ICP) analysis, 1H NMR and FT‐IR techniques. Moreover, the structural and electronic features of metal–ligand interactions in the complex model of polymer‐supported copper nanocatalyst were assessed using density functional theory calculations. The catalytic activity of these supported Cu(I) nonoparticles was examined in one of the classiest name reaction so–called “click reaction” which is coined K. B Sharpless for the regioselective synthesis of 1,2,3‐triazole derivatives using a multicomponent reaction (MCR) involving benzyl halides, sodium azide and terminal alkynes in water as a green solvent. This heterogeneous catalyst showed excellent catalytic activity and was separated by simple filtration and was used at least in five consecutive runs without a significant decrease in its activity.
