Hydroxyapatite supported caesium carbonate as a new recyclable solid base catalyst for the Knoevenagel condensation in water

The Knoevenagel condensation between aromatic aldehydes and malononitrile, ethyl cyanoacetate or malonic acid with hydroxyapatite supported caesium carbonate in water is described. HAP-Cs₂CO₃ was found to be a highly active, stable and recyclable catalyst under the reaction conditions.

Caesium carbonate as a highly efficient catalyst for the synthesis of macrocyclic diamides

In this research work, we report the synthesis of macrocyclic diamides from the reaction of diesters and aliphatic diamines in the presence of caesium carbonate. It has been demonstrated that among the carbonate of alkali metals (Li2CO3, Na2CO3, K2CO3 and CS2CO3), CS2CO3 appear to be the best catalyst for macrocyclization. Diesters with different substitution patterns on the aromatic ring react...

BaO/TiO2-ZrO2 as a green and efficient basic catalyst for Knoevenagel condensation reaction

A simple and green synthetic strategy to prepare BaO/TiO2-ZrO2 as a solid base catalyst was reported. These materials with various amounts of BaO were prepared by the adsorption method. The physical and chemical properties of BaO/TiO2-ZrO2 were investigated by X-ray diffraction, X-ray fluorescence, specific surface area and BJH pore size distribution, FT-IR spectroscopy, scanning electron micro...

Nitrided ITQ-2 as an efficient Knoevenagel condensation catalyst.

The nitrogen-substituted delaminated ITQ-2 zeolite was found to be a highly active and recyclable catalyst for the Knoevenagel condensation of bulky aromatic aldehydes with ethyl cyanoacetate which cannot take place over the base sites placed within the micropores of conventional zeolites due to spatial limitations.
