A robust catalytic system mediates metal‐free and solvent‐free C–C and C–N bond formation by favoring the interaction between the reactants due to the presence of carboxylicacid moieties and chloride counterion, providing a sustainable protocol with appropriate environmental impact.
Sulfuric acid-modified PEG-6000 (PEG-OSO3H): an efficient, bio-degradable and reusable polymeric catalyst for the solvent-free synthesis of poly-substituted quinolines under microwave irradiation
acid-modified polyethylene glycol 6000 (PEG-OSO3H) is applied as an efficient and eco-friendly polymeric catalyst for Friedländer synthesis of poly-substituted quinolines from 2-aminoaryl ketones (or anthranilonitrile) and carbonyl compounds possessing a reactive methylene group undermicrowaveirradiation and solvent-free conditions. The reactions are completed in short times, and the products are obtained

A new family of branched catalysts with hydrocarbon or fluorocarbon chains was used to catalyze Friedländer reaction between 2-aminoarylketones and α-methylene ketones under solvent-free conditions in good to excellent yields. The catalysts exhibit temperature-dependent solubility and such a thermomorphic character allows them to be recovered by filtration conveniently at room temperature and reused

An efficient and eco-friendly synthetic route for Friedländer quinoline synthesis of polysubstituted quinolines is described. This green chemical method starts from various 2-aminobenzophenones and mono- or dicarbonyl synthons and uses reusable Nafion NR50 material as a solid catalyst in ethanol undermicrowaveirradiation. The protocol has a high generality of functional groups and provides the desired

In the present study, for the first time the synthesis of sulfamic acid supported on Fe3O4@SiO2 superpara magnetic nanoparticles as a solid acid catalyst with large density of sulfamic acid groups was suggested. The structural and magnetic properties of functionalized Fe3O4@SiO2 nanoparticles are identified by TEM, IR, VSM, XRD, TGA and elemental analysis. Then, the applicability of the synthesized nanoparticles was tested as a recyclable acidic catalyst for the synthesis of quinoline derivatives, an important class of potentially bioactive compounds. The products are obtained in good to high yields (72–98%) from one-pot reaction procedure involving carbonyl compounds and 2-amino benzophenone under solvent-free conditions.
