A facile synthetic approach to a series of difluoromethylketones from β‐ketoacids has been described. This transformation is achieved through the straightforwarddecarboxylativedifluorination of β‐ketoacids in the absence of any catalyst. Furthermore, the resulted difluoromethylketones can be easily converted into corresponding difluoromethylated building blocks for pharmaceuticals and materials

A practical and novel process for the decarboxylativefluorination of β‐ketoacids in water in the presence of phase transfer catalyst has been developed, affording a series of α‐fluoroketones in good to excellent yields. Furthermore, a preliminary investigation for the catalytic asymmetric transformation was performed and a proposed mechanistic pathway for this catalytic process was proposed.
