十六氟-1，10-癸二醇

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A dry 5 mL round bottom flask was charged with 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9-hexadecafluorodecane-1,10-diol (2.2 mmol, 1.0 g), dry DMF (2.5 mL), and crushed potassium hydroxide (2.2 mmol, 121 mg). The mixture was flushed with argon and benzyl bromide (0.7 mmol, 123 mg) was added dropwise over 15 minutes. The solution was allowed to stir overnight at room temperature under argon. The reaction mixture was concentrated in vacuo, and the residue was partitioned between aqueous saturated ammonium chloride and ethyl acetate. The aqueous layer was extracted twice with EtOAc. The organic layers were combined, washed with water then brine, dried over MgSO4, and concentrated in vacuo. The residue was purified via flash column chromatography on silica gel using 5% EtOAc in petroleum ether as the eluent. The product was isolated as colorless oil; upon drying under high vacuum for 12 h, the oil solidified (90%). 1H NMR (CDCl3): δ7.36 (m, 5H), 4.68 (s, 2H), 4.10 (td, 2H, J=14, 6), 3.94 (t, 2H, J=14), 1.96 (t, 1H, J=7); 13C NMR (CDCl3): δ136.6, 128.8, 128.5, 128.0, 74.7, 66.9, 60.9; 19F NMR (CDCl3): δ −119.8, −122.3, −122.8, −123.7, −123.9. was added dropwise over 15 minutes The reaction mixture was concentrated in vacuo the residue was partitioned between aqueous saturated ammonium chloride and ethyl acetate The aqueous layer was extracted twice with EtOAc washed with water brine, dried over MgSO4 concentrated in vacuo The residue was purified via flash column chromatography on silica gel using 5% EtOAc in petroleum ether as the eluent The product was isolated as colorless oil upon drying under high vacuum for 12 h
