Product Description
Potassium fluoride is widely used as a fluorinating reagent for preparing various organic fluorides. In polar aprotic solvents (such as DMF, DMSO or tetramethylene sulfoxide), aromatic or vinyl groups with electron withdrawing groups can be easily prepared by the exchange reaction of potassium fluoride with aromatic or vinyl chloride.
