Abstract
Bis(fluoroaryl)borane derivative is produced by reacting tris(fluoroaryl)borane with a compound, such as water, ethanol, ammonia and the like, in a hydrocarbon solvent at a molar ratio raging from 1:0.9 to 1:1.1. It is more preferable that the reaction is carried out while the hydrocarbon solvent is distilled off. It is more preferable that hydrocarbon solvent is substantially an aliphatic hydrocarbon solvent. With this arrangement, it is possible to provide a method for producing and isolating the bis(fluoroaryl)borane derivative of a high purity, with ease and at a low cost.
