Background:

• Developing efficient catalysts with reduced noble metal content is crucial for sustainable chemistry.
• Carbon-carbon cross-coupling reactions are fundamental in synthesizing complex organic molecules.
• Noble metal catalysts, particularly palladium, are effective but expensive and scarce.

Purpose of the Study:

• To synthesize and characterize a novel Cu/C-700/Pd nanocomposite catalyst.
• To evaluate the catalytic performance of the Cu/C-700/Pd nanocomposite in Suzuki-Miyaura cross-coupling reactions.
• To demonstrate the advantages of the developed catalyst over existing palladium-based catalysts.

Main Methods:

• Synthesis of a carbon support from a mononuclear copper complex, {[Cu(POP)2(Phen)2]BF4}.
• Loading trace palladium onto the carbon support to form the Cu/C-700/Pd nanocomposite.
• Characterization of the nanomaterial's structure, including copper phosphide and palladium nanoparticles.
• Testing the catalyst's activity and selectivity in Suzuki-Miyaura cross-coupling reactions.

Main Results:

• The Cu/C-700/Pd nanocomposite exhibited excellent catalytic activity (99.73%) and selectivity.
• The catalyst achieved high performance with a very low palladium loading (0.43 mol%).
• The nanomaterial displayed a stable, innovative, and recyclable structure with neighboring Cu-Pd sites.

Conclusions:

• The Cu/C-700/Pd nanocomposite is a highly efficient and selective catalyst for Suzuki-Miyaura cross-coupling.
• This catalyst offers a cost-effective and environmentally friendly alternative due to low noble metal usage.
• The developed nanostructure holds promise for various carbon-carbon coupling reactions and sustainable chemical processes.
