Tetrahydrofuran → HCID 14618903, compound

Participants

Reaction Steps

In the dry box, THF (50 mL) and 4-vinylphenol (5.00 g of a 10% solution in propylene glycol) were added to an oven dry RB flask equipped with a stirrer, Potassium carbonate (0.35 g, 0.0025 mol) was then added. 1,1,1,2,2,3,3-Heptafluoro-3-(1,1,1,2,3,3-hexafluoro-3-(1,2,2-trifluorovinyloxy)propan-2-yloxy)propane (2.70 g, 0.00625 mol) was then added via the addition funnel and the reaction allowed to stir at room temperature. The reaction mixture was heated to a gentle reflux under nitrogen overnight. An aliquot was withdrawn and concentrated under vacuum and analyzed via proton NMR which showed the complete conversion to be 1-(1,1,2-trifluoro-2-(1,1,2,3,3,3-hexafluoro-2-(perfluoropropoxy)propoxy)ethoxy)-4-vinylbenzene. The cooled reaction mixture was then concentrated at reduced pressure taken up in methylene chloride washed with water (˜25 mL) separated, then dried over anhydrous sodium sulfate. The separated organic phase was then concentrated at reduced pressure and then column chromatograph on silica gel obtaining 1.15 g (about 50.0%) of the theoretical yield) of product.
