Outline of Final Research Achievements

We have developed the new heterogeneous base catalysts using their unique properties, such as anion-exchange ability, of layered rare-earth hydroxide. Especially, interlayer space-controlled Y-LRH with alkyl carboxylate anions intercalated into the interlayer has been found to be an effective heterogeneous Bronsted base catalyst for Knoevenagel condensation in water. It can be concluded that the interlayer space of CH3COO-/Y-LRH catalyst expands by the insertion of water molecules, the steric crowding in interlayer decreases, the catalytic reaction proceeds efficiently.
