实验步骤: Hexafluoropropene (264 g, 1.76 mol) was added dropwise to a mechanically stirred mixture of 1,4-cyclohexanedimethanol vinyl ether (300 g, 1.76 mol), acetonitrile (600 mL), and K2CO3 (121 g, 0.88 mol), at 0° C. under N2. The reaction flask was placed in an ice bath to moderate the exothermic reaction during the addition of hexafluoropropene. After complete addition of hexafluoropropene, the reaction mixture was stirred for an additional hour at room temperature and filtered. The filtrate was added to 1.5 L water and mixed well. The lower layer formed was separated, washed with water (3×300 mL), and concentrated under reduced pressure (approximately 0.05 mm Hg) to afford 1,1,2,3,3,3-hexafluoro-1-{[4(vinyloxymethyl)cyclohexyl]methoxy}propane(cis/trans mixture) as a colorless liquid (428 g, 76% yield); b.p. 55-60° C./0.05 mm Hg; Refractive Index 1.4145 at 23.7° C.; GC/MS: m/z at 320 for M+; 19F and 1H NMR spectral data are consistent with the structure.

实验步骤: 4-[(Vinyloxy)methyl]cyclohexylmethanol (2.0 g, 0.010 mol) was dissolved in chloroform (20 mL), cooled to 0° C., and then methanesulfonyl chloride (0.85 mL, 0.011 mol) and triethylamine (1.5 mL, 0.011 mol) were added. The reaction was stirred at 0° C. for 2 hours. The reaction was extracted with ethyl acetate, and the extracts were washed with water, brine, and then dried over MgSO4 and concentrated. The product was purified via column chromatography on silica gel (40% ethyl acetate, 60% hexanes), to give 1.53 g of the desired product as a 3:1 mixture of the two diastereomers. 1H NMR (400 MHz, CDCl3): δ 6.36-6.41 (m, 1H), 4.04-4.10 (m, 2H), 3.94-3.96 (m, 2H), 3.39-3.43 (m, 2H), 2.92 (s, 3H), 0.90-1.80 (m, 10H) (major diastereomer).
