TL;DR: In this paper, a simple, rapid and highly efficient method has been attempted for the three-component condensation of benzil/benzoin, aldehydes, and ammonium acetate under microwave irradiation in the presence of a catalytic amount of bio-supported cellulose sulfuric acid under solvent-free conditions to afford the 2,4,5-triarylimidazole derivatives.

TL;DR: Aromatic carboxylic acids on refluxing with 3,5,6,trichloro-2-pyridyloxyacetylhydrazide in POCl3 gave 5-aryl-2-(3,5-6, trichlorosmethyl)-1,3,4-oxadiazoles, whereas with acid chlorides, acyl(arylsulfonyl)hydrazines were obtained as discussed by the authors.

TL;DR: In this paper, the use of a novel catalyst (i.e., camphor sulfonic acid) in combination with ultrasound technique is reported for the first time, and a comparative study for the synthesis of α-hydroxy and α-amino phosphonates using conventional as well as ultrasonication method is discussed.

TL;DR: 1-Hexanesulphonic acid sodium salt was found to be an efficient catalyst for the green synthesis of alpha-aminophosphonates by the coupling of aldehydes/ketone, an amine and triethyl phosphite under ultrasound irradiation at ambient temperature for appropriate time to furnish the desired product in good to excellent yield under solvent-free condition.

TL;DR: In this article, the catalytic activity of acidic and basic sites present over the microporous molecular sieves has been demonstrated for the efficient synthesis of poly functionalized pyridine derivatives.
