TL;DR: In this paper, a method for synthesizing di-tert-butylphenylphosphonium tetrafluoroborate is presented, which belongs to the field of organic synthesis.
Abstract: The invention discloses a method for synthesizing di-tert-butylphenylphosphonium tetrafluoroborate, and belongs to the field of organic synthesis. The method comprises the following steps: in the anhydrous and anaerobic atmospheres, taking dichlorophenylphosphine as a raw material, after the reduction of diisobutyl aluminium hydride, reacting with tertiary butanol under the catalytic action of boron trifluoride, and then carrying out hydrolysis to generate the di-tert-butylphenylphosphonium tetrafluoroborate. Compared with the prior art, the method is high in yield and simple in aftertreatment, and is more applicable for industrial production.
