Abstract

Organic reactions under solvent-free [1] and aqueous [2] conditions have increasingly attracted chemists' interests, particularly from the viewpoint of green chemistry [3]. As an important carbon-carbon bond forming reaction, Knoevenagel condensation has been extensively studied. Generally, this type of reaction is catalyzed by base or Lewis acid in the liquid-phase system. In recent years, chemists paid more and more attention to the clean ...
