Synthetic studies and p K a measurements are reported on a number of highly fluorinated tertiary alcohols and diols, namely (CF2CF) C (CF3) 2OH,(CF2CF) 2C (CF3) OH,(C6F5) C (CF3) 2OH,(C6F5) 2C (CF3) OH,(C6F5) 3COH,(C6H5) C (CF3) 2OH,[(CF3) 2COH] 2, and [(C6F5) C (CF3) OH] 2. General agreement is found with earlier work reporting a correlation between p K a values and differences between free and H-bonded OH stretching ...
