Methanol → 4,4,5,5,6,6,7,7,7-Nonafluoro-1-heptanol

Participants

Reaction Steps

Borane-methyl sulfide complex (5.2 ml, 52.2 mmol) was slowly added to a solution of 4,4,5,5,6,6,7,7,7-nonafluoroheptanoic acid (5.10 g, 17.4 mmol) in anhydrous tetrahydrofuran (50 ml) at −50° C. The reaction mixture was stirred for 4 hours at room temperature and cooled to 0° C., followed by addition of methanol. After distilling off the solvent, the residue was purified by silica gel column chromatography (eluent: ethyl acetate/hexane=1/5→1/3) to give 4,4,5,5,6,6,7,7,7-nonafluoroheptan-1-ol (4.7 g, Yield 97%) as a colorless oil.
