Preparation of chlorofluorobenzenes and chlorofluoropyridines by halogen exchange with fused salts
Abstract
The reactions of 1,3,5-trichlorotrifluorobenzene, 1,3-dichlorotetrafluorobenzene, and chloropentafluorobenzene with a potassium fluoride–potassium chloride melt are described and compared with similar halogen-exchange reactions under different conditions. The reactions of chlorofluoropyridines with the melt are also described.
