In an article, published in an article, once mentioned the application of 224311-51-7, Name is 2-(Di-tert-Butylphosphino)biphenyl,molecular formula is C20H27P, is a conventional compound. this article was the specific content is as follows.Quality Control of: 2-(Di-tert-Butylphosphino)biphenyl
A preparation method of compound phosphine benzene apperception (by machine translation)
The invention relates to a method for preparing phosphine benzene apperception compound, the bromine compound is made with the magnesium reaction of Grignard reagent, then using four (triphenylphosphine) palladium-catalyzed bromophenylacetic compound phosphine chlorination reaction with the Grignard reagent. The specific method is, under the protection of inert gas, the bromo compound is made with the magnesium chips and organic solvent Grignard reagent, reflux 2 the […] 10 hours; joined four at room temperature (triphenylphosphine) palladium, stirring 10 minutes to 3 hours, chlorinated room temperature instillment phosphine composition, reflux reaction the 1 […] 10 hours; in the ice water bath in the fluid adds by drops full and weak acid to the reaction under weak alkali salt-water solution, liquid, organic phase exsolution, alcohol solvent crystallization, filtering to obtain compound phosphine benzene. The preparation method of this invention not only greatly improves manufacturing yield, and after treatment is simple, the process of repeated washing with ammonia water, the manufacturing process is simplified, is beneficial for large-scale industrial production.
