Abstract:

A novel magnetite nanoparticle-based heterogeneous acidic catalyst [Fe3O4@SiO2@Am-PPC-SO3H] [HSO4] was successfully prepared and characterized by SEM, EDX, TGA, VSM and FT-IR techniques. The magnetically retrievable and sustainable catalyst was investigated in the reaction of aldehyde and o-aminophenol for the synthesis of benzoxazoles. The reactions occurred in water and produced the corresponding products in high yields. The catalyst could be readily separated by an external magnet and showed excellent reusability without significant loss of its activity.

Fe3O4 magnetic nanoparticles were synthesized by co-precipitation of Fe2+ and Fe3+ in aqueous NaOH. Then silica was coated on the obtained nanoparticles and the whole composite was functionalized with chlorosulfonic acid in CH2Cl2. The obtained nanocomposite (Fe3O4@SiO2-SO3H) was characterized by FT-IR, VSM and XRD techniques and was used as an efficient catalyst in condensation reaction of ind...

Silica-bonded n-propyldiethylenetriamine sulfamic acid as a recyclable solid acid catalyst for the synthesis of coumarin and biscoumarin derivatives

Silica-bonded n-propyldiethylenetriamine sulfamic acid (SBPDSA) was found as an efficient solid acid for the synthesis of coumarins. Coumarin derivatives were obtained via the Pechmann condensation reaction of phenols and β-keto-esters at 80 oC under solvent-free conditions. Also, biscoumarins were obtained via the condensation of aldehydes and 4-hydroxycoumarin in water at reflux conditions. T...
