Adding a certain compound to certain chemical reactions, such as: 7681-82-5, name is Sodium iodide, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 7681-82-5, Formula: INa
To a dry round-bottom flask with a stir bar was added 5c (245 mg, 0.983 mmol) and NaI (460 mg, 3.06 mmol). Chlorotrimethylsilane (375 muL, 2.95 mmol) was added dropwise over 5 min at 0C, allowed to stir at 0C for 5 more min, and warmed to rt for 3 hr. The mixture was concentrated, dissolved in ether (25 mL) and 1M HCl (~10 mL), and transferred to a separatory funnel. The aqueous layer was extracted once more with ether (25 mL) and combined organics were washed once with with sat?d NaHSO3 and once with sat?d brine. The organic layer was dried over Na2SO4, filtered, concentrated, and dried in vacuo to afford a dry, white solid 7 (181 mg, 72%) which did not require further purification .1H NMR (CDCl3, 400 MHz) delta 4.52 (s, 2H), 5.06 (s, 2H), 7.29 (d, 1H, J=7.9), 7.51 (d, 1H, J=7.8), 7.75 (s, 1H).13C NMR (CDCl3, 100 MHz) delta 5.47, 71.21, 121.66, 130.50, 131.77, 138.51, 153.53. 11B NMR (CDCl3, 128 MHz) delta 32.24. HRMS (MAII) calc. for C8H8BO2 [M-I]+ 147.0612, found 147.0623.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Sodium iodide, other downstream synthetic routes, hurry up and to see.
