Aerobic ligand-free Suzuki coupling catalyzed by in situ-generated palladium nanoparticles in water

Halide-Enhanced Catalytic Activity of Palladium Nanoparticles Comes at the Expense of Catalyst Recovery

“…This constitutes a second pathway for the formation of leached NPs (NP leach ), which may themselves be catalytically active. This general mechanism is thus also in agreement with work by Saha et al [71] who have shown that Pd NPs can be formed in aqueous solutions of Na 2 PdCl 4 through reduction of the Pd 2+ by aryl boronic acids; this reduction process is precisely the homocoupling reaction studied here but considered from the point of view of the palladium.…”

In-situ synthesis of a palladium-polyaniline hybrid catalyst for a Suzuki coupling reaction

“…It was also found that the reaction did not occur in the absence of Pd nanoparticles [33]. The recovery of the catalyst for the recyclability study was practically not feasible in this study due to the nature of the support and minute amount of the material used for the reaction as a catalyst.Please note that scheme 2 was not cited in the text.…”

Polypyrrole–Palladium Nanocomposite-Coated Latex Particles as a Heterogeneous Catalyst in Water

“…Transitionmetal nanoparticles offer high catalytic efficiency due to their high surface-to-volume ratio. The common method to prepare transition-metal nanoparticles involves the reduction of metal ions in the presence of stabilizers such as surfactants [15,16], polymers [17][18][19] and dendrimers [20][21][22]. When conducting polymers such as polyaniline are used as the support, they also function as the reducing agent and stabilizer [23,24].…”
