TL;DR: In this paper, the authors used Glucosulfonic acid immobilized on Fe3O4 magnetic nanoparticles (GSA@MNPs) for the clean and one-pot synthesis of polyhydroquinoline and 2,3-dihydroquinazolin-4(1H)-one derivatives, with short reaction times in good to high yields in ethanol.

TL;DR: In this article, a simple, catalytic and highly chemo and homoselective oxidation of sulfides to sulfoxides using supported HNO3 on silica gel and poly vinyl pyrrolidone (PVP) in the presence of a catalytic amount of KBr or NaBr was described.

TL;DR: A novel type of recoverable boehmite nanocatalyst was prepared via immobilization of dopamine on the surface of BoE followed by coating with silica and reacting with chlorosulfunic acid to obtain boEmite silica dopamine sulfamic acid (boehmite-Si-DSA), which was characterized by FT-IR spectroscopy, TGA, XRD, TEM and SEM techniques as discussed by the authors.

TL;DR: In this paper, an efficient one-pot three-component condensation of aromatic aldehydes, acetamide and 2-naphtol in the presence of catalytic amounts of MCM-41-N-propylsulfamic acid under thermal solvent-free conditions is described.

TL;DR: In this article, a new copper catalyst was supported on its surface (Cu-ABA@biochar) as reusable and environmental biocatalyst, which has been characterized by SEM, EDS, WDX, XRD, TGA, N2 adsorption-desorption isotherms, FT-IR and AAS techniques.
