METHOD FOR PURIFYING FLUOROARYLBORON DERIVATIVE AND BIS(FLUOROARYL)BORON DERIVATIVE |
摘要 |
<p>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. In a case where the solution contains fluorobenzene, the solution is concentrated, so that the fluorobenzene is removed. Thus, it is possible to provide the high-purity fluoroaryl borane derivative and bis (fluoroaryl) borane derivative having no impurity with ease and at a low cost.</p> |
