Procedure

70 g (1.23 mol) of powdered potassium hydroxide are metered into a solution of 200 g (1.23 mol) of 1,2,3,3,4,4-hexafluorocyclobutene and 90 g (1:5 mol) of isopropanol in 800 ml of diethyl ether at room temperature. The mixture is stirred for a further hour and worked up as described in Example 1. The product is then distilled.
