• KF can also behave as a base in a wide variety of applications:
• Widely used in "halex" fluorination reactions for the preparation of aryl fluorides from the corresponding chlorides by heating in a dipolar aprotic solvent, e.g. tetramethylene sulfone: J. Fluorine Chem., 46, 529 (1990). Other solvents including DMSO, DMA and NMP are also successfully employed. For a review of the preparation of aryl fluorides by halogen exchange, see: Chem. Ind. (London), 518 (1986). Aryl nitro groups can also be displaced in suitable molecules: J. Org. Chem., 56, 6406 (1991). Relative rates for aromatic fluorodenitration in different solvents were found to be: DMSO > tetramethylene sulfoxide > DMA > NMP > tetramethylene sulfone >> acetonitrile > DME: J. Fluorine Chem., 35, 591 (1987).
