[ 1 ] - Modified Biginelli condensation by molybdate sulfuric acid as a powerful and reusable catalyst
Molybdate sulfuric acid (MSA) has been prepared and used as catalyst for the Biginelli synthesis of some quinazolinones/thiones under solvent-free conditions. The catalyst loading is low and it shows recyclability. This method has advantages such as avoidance of the organic solvents, high yield of pure products, short reaction times and operational simplicity.
[ 2 ] - Silica gel: A very cheap, reusable, and efficient catalyst for green preparation of some bis-4-hydroxycoumarin on water
Silica gel has been used for synthesis of biscoumarin derivatives starting from 4-hydroxycoumarin and aryl aldehydes. The reaction conditions are completely in agreement with green chemistry principles including sing water as media and a recyclable and safe catalyst. This method is also simple and inexpensive and leads to high yield of products in short reaction times.
[ 3 ] - Novel One-Pot Synthesis of Pyrazolopyranopyrimidinones Using Newly Produced γ-Alumina Nanoparticles as Powerful Catalyst
g-Alumina nanoparticles (g-Al2O3 NPs) were prepared via a new and simple synthetic route and characterized by field emission scanning electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy. The catalytic activity of prepared g-Al2O3 NPs was investigated for the new one-pot, ...
