Reaction Steps
After dissolving 1.15 g of 3-fluoro-4-nitrophenol in 10 ml of dioxane, the resulting solution was violently stirred at about 60° C. for 15 minutes under the stream of a tetrafluoroethylene gas in large excess of said phenol. After quickly adding 0.04 g of potassium hydroxide, the solution was violently stirred for 2 hours under the same condition. The reaction solution was cooled, and after adding water, extracted with two 100-ml portions of diethyl ether. The ether layers were combined, dried and concentrated to obtain a yellow oily product as a residue. This oily product was subjected to chromatography on silica gel to obtain 0.20 g of 2-fluoro-4-(1,1,2,2-tetrafluoroethoxy)nitrobenzene.
