A common compound: 461-17-6, name is 1,1,1-Trifluoro-4-iodobutane, belongs to iodides-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below. 461-17-6
The alcohol of Example A13 (0.70 g, 1.85 mmol), tetrabutylammonium bromide (119 mg, 0.376 mmol), and KOH (311 mg, 5.55 mmol) were slurried in xylene (7.5 mL). Afterward, 4,4,4-trifluoro-1-iodobutane (1.32 g, 5.55 mmol) was added, and the reaction mixture was stirred in a sealed vial at 80 C. over the weekend. Subsequently, the mixture was filtered through celite and concentrated under N2. Chromatography (on silica, ethyl acetate/hexanes) afforded the ether in the form of a pale yellow oil (551.8 mg, 61.1% yield). NMR(CDCl3) delta 1.19-1.32 (m, 2H), 1.47-1.60 (m, 12H), 1.68 (d, 2H), 1.74-1.84 (m, 2H), 2.05-2.23 (m, 4H), 2.32 (d, 2H), 2.93 (dt, 2H), 3.39 (dt, 2H), 3.43 (dt, 4H), 3.76 (d, 2H), 3.96 (dd, 2H). ESMS m/z=488.42 (M+H)+.
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, 461-17-6, other downstream synthetic routes, hurry up and to see.
