Researchers at the University of Oxford, in collaboration with Pfizer, have developed a method for converting alcohols to alkyl fluorides using potassium fluoride (KF). Their study, published in Science, resolves a challenge in Appel-type fluorination by preventing the formation of the side product PPhF.
The new neopentoxyphosphonium salt enables the production of over 80 fluorinated molecules, including (hetero)cyclic alkyl fluorides, with yields reaching 98%. This method eliminates the need for hazardous hydrogen fluoride and utilizes readily available fluorspar for the fluoride source, enhancing process sustainability. This innovation could significantly impact the fluorochemical industry by promoting a safer, more efficient, and circular economy.
