ChemInform Abstract: Polystyrene-Gallium Trichloride Complex: A Mild, Highly Efficient, and Recyclable Polymeric Lewis Acid Catalyst for Chemoselective Silylation of Alcohols and Phenols with Hexamethyldisilazane.
Tritylium salts have been used as Lewis acid catalyst in organic synthesis for a long time. In this work, we found that the Lewis acid catalytic activity of tritylium ions...
