Application of Sulfonic Acid Functionalized SBA-15 as a Nanoporous Acid Catalyst in Microwave Assisted Synthesis of 2-Aryl Benzoxazoles

Sulfonic acid functionalized SBA-15 as a nanoporous acid catalyst was used in the synthesis of 2-Aryl benzoxazoles 4 by the condensation of 2-aminophenol 1 and benzoyl chlorides 2 under microwave irradiation in solvent free reaction conditions. The advantages of this methodology are good product yields (60-98%), being environmentally benign, short reaction times and easy work up.

Efficient synthesis of 2,3-dihydroquinazolin-4(1H)-ones using nano-sized protonated ZSM–5 as a biodegradable and reusable solid acid catalyst

Nano-sized protonated ZSM–5 ( H-ZSM-5nanozeolite) was successfully synthesized by the hydrothermal method using the bagasse ash (BGA) as a new silica source. Cultivated BGA in the south of the Caspian Sea (Mazandaran province, Iran) was used for extracting silica powder. H-ZSM-5 was characterized by Fourier transform infrared (FT-IR), X-ray diffraction (XRD), scanning electronic microscopy (SEM...

Continuous Synthesis of Oleyl Oleate in Supercritical Carbon Dioxide using Solid p-Toluenesulfonic Acid as Catalyst

Supercritical carbon dioxide (SC-CO2) was used as solvent to synthesize oleyl oleate as an analog of Jojoba oil from oleic acid and oleyl alcohol with high conversion (100%) of the acid into ester in a short time of 100 min. Utilizing a low cost solid catalyst, p-toluenesulfonic acid monohydrate (PTSA), the esterification reaction was performed, without any prior preparation step...

Phospho sulfonic acid: an efficient solid acid catalyst for the facile preparation of 1,4-dihydropyridines

A simple and mild one-pot three-component reaction for the preparation 1,4-dihydropyridines has been developed from various aldehyde substrates, 1,3-dicarbonyl compounds (dimedone) and ammonium acetate (Hantzsch method) in the presence of a catalytic amount of phospho sulfonic acid (PSA) as an efficient and heterogeneous solid acid in EtOH at room temperature. Preparation of PSA is straightforw...
