实验步骤: 4-Cyclohexyl-1-butanol (5.00 g) was dissolved in methylene chloride (100 ml), triphenylphosphine (9.15 g) and N-bromosuccinimide (6.21 g) were added under ice-cooling, and the mixture was stirred under ice-cooling for 1 hr, and further at room temperature for 3 hr. The reaction mixture was washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. Diethyl ether (100 ml) was added, and the precipitated triphenylphosphine oxide was filtered off. The concentrate of the filtrate was purified by silica gel column chromatography (hexane alone) to give the object product (6.30 g) as a colorless oil. cooling cooling for 1 hr The reaction mixture was washed with water and saturated brine dried over anhydrous magnesium sulfate The solvent was evaporated under reduced pressure Diethyl ether (100 ml) was added the precipitated triphenylphosphine oxide was filtered off The concentrate of the filtrate was purified by silica gel column chromatography (hexane alone)

实验步骤: 4-Cyclohexyl-butan-1-ol(8.1 ml, 47 mmol) at -5° C. under nitrogen was treated dropwise over 10-15 min with 2.2 ml (23 mmol) of phosphorus tribromide, stirred at 0° C. for 15 min, room temperature for 2 h, then at 100° C. for 1.5 h before cooling to 0° C. The reaction was quenched with 50 g of ice, diluted with 100 ml of brine, and extracted with ether. The combined organics were washed with brine, dried over anhydrous sodium sulfate, filtered, concentrated, and distilled at 2 mm Hg, 100° C., to give 9.84 g (96%) of 1-bromo-4-cyclohexylbutane as a colorless liquid. NMR (CDCl3, TMS) δ 0.6-2.3 (m, 17H), 3.43 (t, J=7 Hz, 2H). at 100° C. for 1.5 h before cooling to 0° C The reaction was quenched with 50 g of ice diluted with 100 ml of brine extracted with ether The combined organics were washed with brine dried over anhydrous sodium sulfate filtered concentrated distilled at 2 mm Hg, 100° C.
