ACETIC ACID-D4 - Reference Information
| Using | Irfana Jesin et al, sulfonimide amides have been studied as directing agents for the regioselective oxidation of C- H acyloxylation of aromatic hydrocarbons catalyzed by Pd. CN201811344212.6 reported the use of acetic acid-D3 for the preparation of the above compounds, useful as MEK inhibitors. |
| Overview | acetic acid-D3 is also called acetic acid -2,2,2-d3. Perrin et al. reported that acetic acid-D3 can be prepared in one step from Malonic-d2 acid-d2. |
| preparation method | malonic acid-d2 acid-d2(2.7g,25mmol) in 140.MAL E.C was thawed at temperature and then water was added (112.5 μL,6.25mmol with stirring). The mixture was heated to 150.MAL E.C. After 15 min, the colorless liquid (1.32g,85%) was collected by distillation at atmospheric pressure. The product was stirred with 0.2mL D2O, the water was pumped out, and the sample was dried under vacuum with a cold trap. The product was further purified by fractional distillation under atmospheric pressure in a closed drying system to give 0.61G of product. 1H NMR of the product revealed three sets of signals with an integration ratio of 3.6%:31.2%:65.2%, corresponding to acetic acid: acetic acid-acetic acid: acetic acid -2 acid. 1 H NMR(500 MHz,D2O) Δ1.95 (s,CH3),1.93(t,J = 2.5Hz,CDH2),1.92(q,J = 2.0Hz,CD2H). Since the ratio of D:H in the reaction mixture was 8:1, the product also contained> 50% of acetic acid-d3, which was not visible in 1H NMR. 13 C NMR(D2O) Δ176.5, 20.2 (five by weight). |
| preparation method 2 | Arrowsmith et al. reported that acetic acid-D3 can be prepared from acetic acid-D4 by removing one deuterium under the action of methanol. |
| autoignition temperature | 800 ° F. |
