7025-19-6, A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.7025-19-6, name is 3-(4-Oxo-2-thioxothiazolidin-3-yl)propanoic acid. An updated downstream synthesis route of 7025-19-6 as follows.
[0050] To a solution of 2-thiazolidinone (4.15 g, 40.18 mmol) in acetonitrile (60 ml) were added potassium carbonate (13.3 g 96.2 mmol), N,N-dimethyl-3-aminopropyl chloride hydrochloride (7.63 g, 48.3 mmol), and 18-crown-6 (catalytic amount). The mixture was refluxed for 18 hours, solvent removed in vacuo, then redissolved in dichloromethane and 1 M potassium chloride (40 ml each). The aqueous phase was isolated and extracted twice with 30 ml portions of dichloromethane. The combined organic fraction was washed with saturated sodium chloride (50 ml), dried over sodium sulfate, filtered, and dried in vacuo. The crude product was purified via silica gel chromatography, using a 10:1 ratio of silica gel A, 200-425 mesh, and eluting with 5% methanol in chloroform, yielding 1.15 g (15%) pure product.
In every case, we must determine the overall rate law from experimental data and deduce the mechanism from the rate law (and sometimes from other data). you can also browse my other articles about Thiazolidin-2-one if you are interested.
