Synthesis of Pd/SiO2 Nanobeads for Use in Suzuki Coupling Reactions by Reverse Micelle Sol–gel Process

Pd/SiO 2 nanobeads containing tiny Pd clusters with a diameter of about 2 nm were prepared via a sol–gel process for SiO 2 by using a water-in-oil microemulsion with Pd complexes and subsequent hydrogen reduction by heat treatment. The Pd/SiO 2 nanostructures were employed in Suzuki coupling reactio...

Zusammenfassung:	Pd/SiO 2 nanobeads containing tiny Pd clusters with a diameter of about 2 nm were prepared via a sol–gel process for SiO 2 by using a water-in-oil microemulsion with Pd complexes and subsequent hydrogen reduction by heat treatment. The Pd/SiO 2 nanostructures were employed in Suzuki coupling reactions with various substrates, and they served as good catalysts in these reactions. Graphical Abstract
