Palladium Nanoparticles Immobilized on Newly Modified Sol-Gels: Excellent Catalysts for Cross-Coupling Reactions

Using mixed combination of N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (AAPTMOS) and vinyl tetraethoxysilane (VTEOS) or the presence of phosphorylated imidazolium based ionic liquid in the sol-gel formation provides an excellent surface for the formation of highly dispersed, uniformly sized Pd nanocatalysts. These nanoparticles which are tightly supported on the surface of the silica have been applied for the efficient cross-coupling reactions.
