250mL three-necked flask cyanoimino-1,3-thiazolidine 3.4 g (0.0265mol), and treated with 150 mL of acetonitrile was stirred, after dissolved with K2CO3 3.7g (0.0265mol), a solution of 5.3 g (0.0265 mol) of diethoxy thiophosphoryl chloride (94%) in 50 mL of acetonitrile was slowly added dropwise, 15 min within the drop is completed, heating to 45C for 13 h. After completion of the reaction, the filtrate was concentrated to give a yellow oil which was passed through a silica gel column (V petroleum ether: V ethyl acetate = 7: 3). Recrystallization from ethyl acetate gave a colorless transparent crystal L090813. Melting point 49.2-51.5 C, yield 76.9%.

General procedure: A solution of 0.002 mol of rhodanine in 5 mL of ethanol and 0.05 mL of 2-aminoethanol were added to a solution of 0.002 mol of aldehyde 1 in 5 mL of ethanol. The mixture was refluxed for 2-3 h and cooled. The precipitate was filtered off and recrystallized.

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.

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.

General procedure: A mixture of aminorhodanine (1 mmol), isatin (1 mmol) and 5 muL of acetic acid in 2mL of distilled ethanol was placed in a cylindrical quartz reactor (Phi = 4 cm). The reactor was introducedinto a monomode microwave (Anton Paar) apparatus, for 5 min at100 C and 50 Watts. The crude reaction mixture was allowed tocool down at room temperature and ethanol (10 mL) or mixture of H2O/EtOH (10 mL) was directly added in the cylindrical quartzreactor. The resulting precipitated product was filtered off and waspurified by recrystallization from ethanol if necessary.
