Reaction Steps

According to scheme (27) above, in a flask that can be equipped with an agitator, thermocouple and a reflux condenser, 20 grams (27 mmol) of 1,1,1,2,4,4,6,6-octafluoro-2,8,10,12-tetrakis(trifluoromethyl)-14-iodotetradecane (see, e.g. Published Patent Applications), 20 ml of absolute ethanol, 3.9 grams (40.5 mmol) of potassium thiocyanate (KSCN) and 0.5 ml of glacial acetic acid (HOAc) can be placed to form a mixture. The mixture can be heated to reflux (84.7 C) and maintained stirring for overnight. The mixture can be concentrated in vacuo to afford what can be observed as a thick yellow slurry. The slurry can be extracted with 300 ml of diethyl ether and decanted twice and filtered to afford a wet cake and a filtrate. The wet cake can be washed with three 100 ml portions of diethyl ether and the filtrates combined. The combined filtrates can be concentrated in vacuo to afford 17.12 grams (94.6% yield) of the 1,1,1,2,4,4,6,6-octafluoro-2,8,10,12-tetrakis(trifluoromethyl)-14-thiocyanatotetradecane product that can be observed as a light yellow oil. The product structure can be confirmed by NMR and/or chromatographic analysis.
