    摘要: A (fluoroaryl)borane compound expressed by General Formula (1): ##STR1## where each of R.sub.1 -R.sub.5 represents a hydrogen atom, a fluorine atom, a hydrocarbon group, or an alkoxy group, provided that at least one of R.sub.1 -R.sub.5 represents a fluorine atom, X represents a fluorine atom, a chlorine atom, a bromine atom, or an iodine atom, and n represents 2 or 3, is stabilized by letting inorganic metal salts having a fluorine atom coexist with the (fluoroaryl)borane compound in a hydrocarbon solution. After the hydrocarbon solution is concentrated in the presence of the inorganic metal salts, the inorganic metal salts are removed and the fluoroaryl)borane compound is crystallized. Consequently, it has become possible to provide a method of stabilizing a (fluoroaryl)borane compound by suppressing the decomposition reaction while the solution is heated and concentrated, stored (preserved), or transported/transferred, and a crystallizing method of isolating highly-pure crystals (powders) of the (fluoroaryl)borane compound efficiently.

    摘要: 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.
