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.

Method for synthesizing di-tert-butylphenylphosphonium tetrafluoroborate

The invention discloses a method for preparing a diarylphosphochlorine compound and belongs to the field of organic synthesis. The method is as follows: the diarylphosphochlorine compound is preparedby reaction of triarylphosphine as a starting material with phosphorus trichloride in the presence of zinc trifluoromethanesulfonate as a catalyst and distillation. Compared with the prior art, the method has the advantages of high reaction yield and simple post-treatment, is particularly suitable for preparation of the diarylphosphochlorine compound with a substituent, and is more suitable for industrial production. The obtained diarylphosphochlorine compound can be used as a ligand for synthesizing metal catalysts, and is applied to the fields such as organic photoelectric materials and medicines.
