Designed Synthesis of Atom-Economical Pd/Ni Bimetallic Nanoparticle-Based Catalysts for Sonogashira Coupling Reactions

Abstract

We synthesized Ni/Pd core/shell nanoparticles from the consecutive thermal decomposition of metal-surfactant complexes. The nanoparticle catalyst was atom-economically applied for various Sonogashira coupling reactions.

Suzuki-Miyaura Cross-coupling Reaction Catalyzed by Nickel Nanoparticles Supported on Poly(N-vinyl-2-pyrrolidone)/TiO2-ZrO2Composite

“…[1][2][3][4] Usually, carbon-carbon coupling reactions are catalyzed by palladium compound [5][6][7] or Ni-Pd bimetallic catalysts. [8][9][10][11][12][13] On the other hand, the Ni catalysts have many advantages over the Pd catalyst, for example, they are more reactive and often cheaper than the Pd complexes. 14,15 Ni catalyzed reactions are more specific and are complementary to their Pd analogues.…”

Properties, Characterizations and Applications of Organometallic Surfactants—A Review

“…Transitional metal containing materials are more commonly known and these are typically first or second raw transition metals (d-block elements of the periodic table) with other accounts involving the lanthanides. Most of the surfactants that fall under the transition metal category contain one or more of elements including Scandium (Sc) [7], Titanium (Ti) [8]- [10], Vanadium (V) [10] [11], Chromium (Cr) [9], Iron (Fe) [12] [13], Cobalt (Co) [14], Nickel (Ni) [15], Copper (Cu) [16], Zinc Zn [17], Yttrium (Y) [9], Zirconium (Zr) [8] [18] [19], Niobium (Nb) [20], Palladium (Pd) [15], Silver (Ag) [6], Lanthanum (La), Europium (Eu), Gadolinium (Gd), Ytterbium (Yb) [21], Hafnium (Hf) [8] and Osmium (Os) [22]. Similarly, there are a number of reports on non-transition metal-based organometallic surfactants.…”

“…Those from the Palladium precursors were much smaller than those from their Nickel counterparts. The researchers concluded that Palladium nanoparticles are more difficult to synthesize than those of Nickel, because Nickel metal was easier to form in the synthetic technique they employed [15]. Although there are various methods of preparing nanoparticles for various applications, the use of organometallic surfactant precursors is considered to generate products with better characteristics compared to those from other routes [36].…”

Environmentally-Safe Catalytically Active and Biocide Polymer-Metal Nanocomposites with Enhanced Structural Parameters

“…Pd@Co MNPs synthesized in different polymeric matrices have been tested as catalysts for various cross-coupling reactions (Table 1, Figure 11) (Son et al, 2004), although they can also be applied as catalysts in other processes like dehalogenation, hydrodechlorination, carbonylation or oxidation (Wilson et al, 2006;Umpierre et al, 2005).
