Abstract
A method for easily and inexpensively producing and purifying a fluoroaryl metal compound such as bis(pentafluorophenyl)dialkyltin which is less colored and has no impurities is provided. Hydrocarbon magnesium halide is reacted with fluoroaryl halide in a solvent including an ether solvent so as to obtain fluoroaryl magnesium halide, which is then reacted with an organic metal compound so as to produce a fluoroaryl metal compound. Tin is more preferable as a metal atom included in the organic metal compound. As for the ether solvent, chain ether solvents are preferable, more specifically, diisopropyl ether, dibutyl ether, and t-butylmethyl ether are more preferable. Besides, it is preferable that magnesium halide, which is a by-product of the fluoroaryl metal compound, is precipitated and removed, or treated with an acid.
