Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.26364-65-8, name is 2-Cyanoimino-1,3-thiazolidine,below Introduce a new synthetic route., 26364-65-8
1,2-thiazolidine 1,1-dioxide (0.03 I g, 0.259 mmol) in dimethylformamide (1 mL) was treated with 60% sodium hydride (0.012g, 0.518 mmol, 0.021 g of a 60% in oil dispersion).The reaction mixture was stirred for 5 mm. To this solution was added Example 41b (0.05 g,0.086 mmol). The reaction mixture was stirred at room temperature for 2 hours. 2 N NaOH (1 mL) was added and the reaction mixture was heated at 65 C for 2 hours. After cooling to room temperature, the reaction mixture was partitioned between water and ethyl acetate. The aqueous layer was extracted with additional ethyl acetate twice. The combined organic layerswere washed with brine, dried over MgSO4, filtered, and concentrated. The residue was purified by preparative HPLC (C18, 10-80% acetonitrile in 0.1% TFA water) to afford 0.025 g (64%) of the title compound. 1H NMR (500 MHz, DMSO-d6) 2.21-2.25 (m, 2H), 3.15 (t, J=6.97 Hz, 2H), 3.23-3.27 (m, 2H), 3.50 (s, 3H), 4.13 (s, 2H), 6.25-6.26 (m, IH), 6.88 (d, J=7.63 Hz, 2H), 7.00 (d, J8.54 Hz, 1H), 7.03-7.05 (m, IH), 7.25-7.30 (m, 4H), 7.34 (dd,J=8.39, 2.29, ZH), 7.48 (d, J=2.44 Hz, 1H), 12.00 (s, 1 H). MS (ESI+) m/z 450.2 (M+H).
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 5908-62-3
