Employing a hydrophobic-bentonite as a highly efficient and versatile catalyst for a green one-pot and rapid synthesis of 4H-benzo-[b]-pyran derivatives
A hydrophobic-bentonite catalyst (cetyltrimethyl ammonium bromide-bentonite) has been used as a very mild, neutral, eco-friendly, reusable, non-toxic, low-cost and easily available catalyst. It was prepared by replacing the exchangeable Na+ cations of a homoionic Na–bentonite with cetyltrimethyl ammonium bromide (CTMAB) cations. The catalyst was characterized by XRD, BET and SEM. The...

متن کاملA Convenient Procedure for Friedlander Synthesis of Quinoline Derivatives Catalyzed by Zirconium Dodecylphosphonate as an Efficient and Reusable Catalyst
2-Amino-substituted ketones react with α-methylene ketones under solvent-free conditions at 90 °C in thepresence of a catalytic amount of zirconium dodecylphosphonate to create the corresponding quinolinesin excellent yields. This procedure recommends numerous advantages such as easy work-up, use of mild,reusable and safe catalyst, short reaction timeand high yields. The new compounds have been...
متن کاملCo3O4 nanoparticles as a robust and recoverable catalyst for one-pot synthesis of polyhydroquinolines and tetrahydrobenzopyrans
This study introduces a green and efficient method for preparation of biologically-active substituted 4H-pyrans using the one-pot three-component reaction of aromatic aldehydes, dimedone and malononitrile in the presence of cobalt oxide nanoparticles. Co3O4 nanoparticles were used as an efficient catalyst for the synthesis of polyhydroquinoline derivatives by the reaction ...
