Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 2043-57-4, name is 1,1,1,2,2,3,3,4,4,5,5,6,6-Tridecafluoro-8-iodooctane, A new synthetic method of this compound is introduced below., Product Details of 2043-57-4
1-Methylimidazole (4.32 g, 0.52 mol) was partially dissolved in reagent-grade toluene (50 ml) in a large round-bottomed flask and stirred vigorously. 1,1,1,2,2,3,3,4,4,5,5,6, 6-Tridecafluoro-8-iodooctane (26 g, 0.053 mol) was added, and the mixture was heated under reflux at 110 degrees C for 24 hours. The solvent was removed under vacuum giving l-methyl-3- (3,3,4,4,5,5,6,6,7,7,8,8,8- tridecafluorooctyl) imidazolium iodide (30.5 g) as a waxy solid. Potassium 1,1,2,2- tetrafluoroethanesulfonate (TFES-K, 12 g) was added to reagent grade acetone (100 ml) in a separate round- bottomed flask, and this solution was carefully added to the l-methyl-3- (3,3,4,4,5,5, 6, 6,7,7, 8, 8, 8- tridecafluorooctyl) imidazolium iodide which had been dissolved in acetone (50 ml) . The reaction mixture was heated under reflux for approximately 16 hours. The reaction mixture was then filtered using a large frit glass funnel to remove the white KI precipitate formed, and the filtrate was placed on a rotary evaporator for 4 hours to remove the acetone. The oily liquid was then filtered a second time to yield the product, as shown by proton NMR.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
