Optimization of compound lipophilicity is a key aspect of drug discovery. The aim of this work was to compare the lipophilicity modulations induced by 16 distinct known and novel fluoroalkyl motifs on three parent models. Fifty fluorinated compounds, with 28 novel experimental aliphatic log P values, are involved in discussing various lipophilicity trends. As well as confirming known trends, a number
A process for the preparation a fluorinated acid of the formula R

is independently selected from linear, branched or cyclic hydrocarbyl of 1-12 carbon atoms having 1-25 fluorine atoms and any range there between; and wherein the contacting step is carried out in the presence of a catalyst and optionally in a reaction medium, at a temperature and length of time sufficient to produce the fluorinated acid.
Provided are methods of producing fluorinated alcohols from non-perfluorinated fluoroolefins and methanol. Certain preferred embodiments of such methods involve advantageously reacting a non-perfluorinated fluoroolefin with methanol under ambient-pressure and/or low-temperature conditions.
