Sol–gel immobilized aryl iodides for the catalytic oxidative α-tosyloxylation of ketones

Metal-free chemoselective oxidation of sulfides to sulfoxides catalyzed by immobilized l-aspartic acid and l-glutamic acid in an aqueous phase at room temperature

Immobilized l-aspartic and l-glutamic acid were employed in the oxidation of sulfides, and 99% conversion and 97% selectivity were achieved.

Surface immobilization of β-cyclodextrin on hybrid silica and its fast adsorption performance of p-nitrophenol from the aqueous phase

Fast adsorption of p-nitrophenol was achieved through surface immobilization of β-cyclodextrin onto hybrid silica and maintenance of its hydrophobic cavity.
