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 trifluoromethylated symphony! A new transformation involving trifluoromethyl diazomethane generated in situ has been developed that allows direct access to trifluoroethyl ketone derivatives from aldehyde and cyclohexanone compounds (see scheme).
