Abstract
In a method for purifying a fluoroaryl metal compound of the present invention, magnesium halide is precipitated and removed from a solution containing the fluoroaryl metal compound, the magnesium halide, and an ether solvent. Or, the magnesium halide is removed by treating the solution with an acid. Examples of the method include: a method in which a solvent which has a boiling point higher than that of the ether solvent contained in the solution and which does not dissolve the magnesium halide is heated to a temperature higher than the boiling point of the ether solvent, then the ether solvent is distilled out with the solution being added to the solvent; and a method in which the solution and an aqueous solution containing an acid are mixed and stirred, then allowed to stand so as to be separated into an organic layer containing the fluoroaryl metal compound and an aqueous layer containing the magnesium halide and the acid. In this manner, a highly pure fluoroaryl metal compound having no impurities can be purified easily and inexpensively.
