Application of 592-55-2, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 592-55-2 name is 1-Bromo-2-ethoxyethane, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
To a solution of 1,3-dithiane (1.02 g, 8.51 mmol) in THF (20 mL) under nitrogen at -3O0C was added n- BuLi in hexanes (4.90 mL, 1.6 M, 7.84 mmol) dropwise. The reaction was left for 2 hours at this temperature then was cooled to -780C when a solution of 2-bromoethyl ethyl ether (0.80 mL, 7.09 mmol) in THF (5 mL) was added dropwise. The reaction was then left to warm to room temperature and stir for 18 hours. The reaction was quenched with 10% citric acid (12 mL) and diluted with ethyl acetate (70 mL) . The aqueous phase was extracted with ethyl acetate (2 x 10 mL) . The combined organic phase was dried, filtered and the solvent removed in vacuo. This material (1.43 g) was dried onto silica gel then purified by flash chromatography, eluting with petroleum spirit/ethyl acetate (9:1) to afford, as a yellow oil, 2- (2-ethoxy-ethyl) – [1,3] dithiane (0.49 g, 36%). 1H NMR (CDCl3, 400 MHz) delta= 1.20 (t, J = 7.0 Hz, 3H), 1.80- 1.94 (m, IH), 2.02 (q, J= 6.4 Hz, 2H), 2.08-2.18 (m, IH), EPO
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1-Bromo-2-ethoxyethane, and friends who are interested can also refer to it.
