2-aryl-piperidines can be ring-opened with the reagentcombination of tetrabutylammonium fluoride (TBAF) and potassium bifluoride (KHF2) in a regioselective and divergent fashion. Four different types of hydroxylated fluoro-piperidines, valuable building blocks in drug development, were readily synthesized using this method. The basic nature of the reagentcombination allowed a one-pot deprotection/ring opening
