Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 827-08-7, name is 1,2-Dibromo-3,4,5,6-tetrafluorobenzene, This compound has unique chemical properties. The synthetic route is as follows., COA of Formula: C6Br2F4
EXAMPLE 1 1,4-bis(dipentafluorophenylboryl)-2,3,5,6-tetrafluorobenzene 1.54 g (5 mmol) of dibromotetrafluorobenzene are dissolved in 40 ml of n-hexane and cooled to -78 C. 6.4 ml of n-BuLi (10 mmol) are slowly added dropwise to the solution and the mixture is stirred for 1 hour. Subsequently, 1.90 g (5 mmol) of bis(pentafluorophenyl)borylchloride are dissolved in 40 ml of n-hexane and likewise added dropwise to the above solution. The suspension obtained is slowly warmed to room temperature, forming a white precipitant. This is separated off by filtration and the filtrate obtained is evaporated to dryness under reduced pressure. The yield of the resulting 1,4-bis(dipentafluorophenylboryl)-2,3,5,6-tetrafluorobenzene obtained as a yellow oil is 81%.
According to the analysis of related databases, 827-08-7, the application of this compound in the production field has become more and more popular.
