PCT No. PCT/JP97/00391 Sec. 371 Date Oct. 16, 1997 Sec. 102(e) Date Oct. 16, 1997 PCT Filed Feb. 12, 1997 PCT Pub. No. WO97/31924 PCT Pub. Date Sep. 4, 1997A 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.
