An innovative route for synthesis of 2-thioxo-2,3-dihydroquinazolin-4(1H)-ones using isatoic anhydride and Ph isothiocyanate via in-situ formation of anthranilic acid was described. The reaction was performed in the nano-micellar assembly of surfactant, 4-(dimethylamino)-1-hexadecylpyridinium hydroxide [DAHP]+[OH]– as a nano-reactor. The micelle concentration of surfactant is found to be 0.002 mol.dm-3 using the conductivity data. The micellar particle dimensions were demonstrated from small-angle X-ray scattering (SAXS) anal. viz. micelle diameter and the interspacing between two micelles which were found to be 14.8 nm and 2.6 nm, resp. From the TGA anal., the surfactant is thermally stable up to 250°C with 76.01% weight loss. The practical simplicity, atom economy, good to high yields, ease of product isolation and purification, water as eco-benign solvent and catalyst recyclability were the remarkable aspects of the present methodol. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Product Details of 2253-73-8).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Product Details of 2253-73-8
