Gold Nanostructures Stabilized on Layered Polydimethylsiloxane-Like Porous Silica Framework as a Solvent-Free Heterogeneous Catalyst for Hydroamination
Bifaceted building blocks possessing a layered hydrophobic polydimethylsiloxane (PDMS)-like framework and segment-enriched silica network with permanent porosity have been crafted for hosting and stabilizing gold nanoparticles. The as-prepared solid materials were used as heterogeneous catalysts for solvent-free hydroamination. Unlike mesostructured-type and conventional silica supports, the more pronounced hydrophobicity of PDMSiO2 provides the driving force for preventing imine hydrolysis, allowing consequently for improving the yield to 94% and selectivity to 99%.
