Abstract: After a fluoroaryl borane derivative is precipitated from a solution containing the fluoroaryl borane derivative, a bis (fluoroaryl) borane derivative, and a hydrocarbon solvent and is subjected to first filtration so that the fluoroaryl borane derivative is isolated, a filtrate that has been obtained by the first filtration is cooled and the bis (fluoroaryl) borane derivative is separated and is subjected to second filtration so that the bis (fluoroaryl) borane derivative is isolated.
