Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 1,1′-Dibromoferrocene, 1293-65-8
1293-65-8, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 1,1′-Dibromoferrocene, cas is 1293-65-8,the iron-catalyst compound, it is a common compound, a new synthetic route is introduced below.
Example L:Preparation of (RC,SFC,SP)-1 -[2-(1 -dimethylaminoethyl)ferrocen-1 -yl]phenylphosphino-1 ‘-bromoferrocene of the formula (B1 ) [Ph = phenyl; Me = methyl].N MthetaQ diastereomers One diastereomer a) Preparation of i -phenylchlorophosphine-i ‘-bromoferrocene (X1 ).At a temperature of <-30C, 14.5 ml (23.2 mmol) of n-butyllithium (n-Bu-Li) (1.6 M in hexane) are added dropwise to a solution of 8 g (23.2 mmol) of 1 ,1 '-dibromoferrocene in 30 ml of tetrahydrofuran (THF). The mixture is stirred at this temperature for a further 30 minutes. The mixture is then cooled to -78C, and 3.15 ml (23.2 mmol) of phenyldichlorophosphine are added dropwise at a sufficiently slow rate that the temperature does not rise above -600C. After stirring at -78C for a further 10 minutes, the temperature is allowed to rise to room temperature, and the mixture is stirred for another hour. A suspension of the monochlorophosphine X1 is thus obtained.
