26364-65-8, 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.26364-65-8, name is 2-Cyanoimino-1,3-thiazolidine. An updated downstream synthesis route of 26364-65-8 as follows.

General procedure: Under N2 atmosphere, NaH (120 mg, 60% dispersion in mineral oil, 3 mmol)was added to a solution of thiazolidine-2-thione 2 (2.5 mmol) in 5 mL of THF and the resulting solution was cooled to 78C by a dry-ice-acetone bath. Propionyl chloride(255 mg, 2.5 mmol, 480 muL) was then dropped in. After removal of the solvent in vacuo,the residue was purified by column chromatography with a mixture of petroleum ether(60-90C)/EtOAc (5:1, v/v) as eluent., 185137-29-5

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 (S)-4-Phenylthiazolidine-2-thione if you are interested.

An updated downstream synthesis route of 26364-65-8 as follows., 26364-65-8

General procedure: To thiazolidine-2-thiones (1.0 equiv.) in THF (5.5 mL/mmol), 60% NaH dispersion in mineral oil (1.2 equiv.)was slowly added at 0 C. The reaction mixture was stirred for 15 min at 0 C before acetyl chloride (1.2 equiv.)was added dropwise. The reaction mixture was stirred for 30 min at 0 C, upon which it was warmed to roomtemperature and allowed to stir for another 2 h. The reaction was quenched with saturated NH4Cl (3 mL/mmol)and the layers were separated. The aq. layer was extracted with EtOAc (2 x 4 mL/mmol) and the combinedorganic layers were dried (Na2SO4),filtered, and concentrated in vacuo. The crude product was purified bycolumn chromatography on silica (hexanes/EtOAc 8:2) to afford the title compounds as yellow oils.

There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps. you can also browse my other articles about 185137-29-5

Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.19771-63-2, name is (R)-2-Oxothiazolidine-4-carboxylic acid,below Introduce a new synthetic route., 19771-63-2

General procedure: Thiazolidine-2-thione 2 (2.5 mmol), benzyl chloride (317 mg, 2.5 mmol), and K2CO3(691 mg, 5 mmol) were dissolved in 10 mL of acetone. The resulting solution was refluxedfor 2-4 h under TLC monitoring and then was allowed to cool to r.t. and filtered. Afterremoval of the solvent, the crude product was obtained and purified by silica-gel columnchromatography with a mixture of petroleum ether and EtOAc (10:1, v/v) as eluent.

Any one of these steps may be slow and thus may serve as the rate determining step. In general, however, in the presence of the catalyst, the overall rate of the reaction is faster than it would be if the reactants were in the gas or liquid phase.
