Abstract
A fluoroaryl magnesium derivative is produced by reacting aryl fluoride, hydrocarbon halide, and magnesium with one another in an ether solvent or a mixed solvent of the ether solvent and a hydrocarbon solvent. Also, a (fluoroaryl)borane compound is produced by mixing both a solution prepared by dissolving the fluoroaryl magnesium derivative into the ether solvent and another solvent prepared by dissolving the boron halide in the ether solvent with a hydrocarbon solvent having a higher boiling point than the ether solvent, so that the fluoroaryl magnesium derivative and boron halide react with each other while the ether solvent is being distilled out.
