Aliphatic alcohols that contain a high percentage of fluorine are more acidic than the corresponding fluorinefree alcohols' and thus would be expected to be stronger hydrogen- bonding acids2 The most pronounced effects would be observed in alcohols containing fluorine bonded directly to the a-carbon. One such alcohol, perfluorocyclobutanol, has been prepared, and nmr studies indicate that it is internally hydrogen bonded. However, this ...
