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. 647-42-7, name is 3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctan-1-ol. A new synthetic method of this compound is introduced below., Safety of 3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctan-1-ol
To a solution of the perfluoroalkyl alcohol (10 mmol) in 10 mLof dry THF, was added sodium hydride (60% 1.4 equiv. dissolved in 2 mL of dry THF in oil) at 0 C under nitrogen atmosphere. The mixture was stirred for 30 min. Then 1.35 g (10 mmol) of henylisothiocyanate was added. The reaction mixture was allowed to warm to room temperature and stirred for 3 h. The mixture was quenched with saturated aqueous ammonium chloride. The aqueous layer was washed with diethyl ether and the combined organic layers were dried over Na2SO4. The solvent was removed by vacuum evaporation and the crude products were purified with column chromatography on silica gel (70-230 meshes) using petroleum ether/diethyl ether (8:2) as eluent or recrystallized in cyclohexane to give the corresponding O-perfluoroalkyl thiocarbamate.
