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...

متن کامل[BMIm]HSO4 as a Green and Highly Efficient Catalyst for One-pot Synthesis of 3-Substituted Indoles under Ultrasound Irradiation
A practical and green synthesis of 3-substituted indoles is reported via three-component coupling reaction of indoles, aldehydes and N-methylaniline in the presence of the acidic ionic liquid 1-butyl-3-methylimidazolium hydrogen sulfate ([BMIm]HSO4) under ultrasound irradiation at room temperature. The significant features of this procedure are high yields of the products, simple work-up, opera...
متن کاملNitrided 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.
