Abstract
Calix [4] arene scaffold based quaternary ammonium salts as multi-site phase transfer catalysts were prepared and their catalytic activities were investigated for Darzens condensation, O/N-alkylation reactions and ethyl benzene oxidation. These calix [4] arene based multi-site phase transfer catalysts showed significant high catalytic activity as compared to single-site phase transfer catalysts.
