355-80-6, 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. 355-80-6, name is 2,2,3,3,4,4,5,5-Octafluoro-1-pentanol. A new synthetic method of this compound is introduced below.
General rocedure: 5.5 ml of aq. solutions of KBr (0.55 mol/dm3), 20 ml MeCN, TEMPO (0.12 g, 0.00077 mol), and 2,2,3-trifluoro-3-(1,1,2,2,3,3-hexafluoro-3-trifluoromethoxy-propoxy)-propan-1-ol (2a) (10 g, 0.0275 mol) were placed in the flask. 14% aq. NaOCl (48 ml) buffered by NaHCO3 (5.2 g) were added via the dropping funnel in 3 portions during two days of stirring in a room temperature (slight exothermic effect). The progress of reaction was monitored by 19F NMR spectroscopy. Then concentrated sulfuric acid followed by water was added. After extraction with diethyl ether, the organic phases were dried over magnesium sulfate. The solvent was evaporated to give a colorless liquid, which was distilled.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,355-80-6, 2,2,3,3,4,4,5,5-Octafluoro-1-pentanol, and friends who are interested can also refer to it.
