With the complex challenges of chemical substances, we look forward to future research findings about 1,1′-Dibromoferrocene
As a common heterocyclic compound, it belongs to iron-catalyst compound, name is 1,1′-Dibromoferrocene, and cas is 1293-65-8, its synthesis route is as follows.,1293-65-8
Example L; Preparation of (RC,SFC,SP)-1 -[2-(1 -dimethylaminoethyl)ferrocen-1 -yl]phenylphosphino-1 ‘-bromoferrocenes of the formula (A1) [Ph = phenyl; Me = methyl]; a) Preparation of i -phenylchlorophosphine-i ‘-bromoferrocene (X1); To a solution of 8 g (23.2 mmol) of 1 ,1’-dibromoferrocene in 30 ml of tetrahydrofuran (THF) are added dropwise, at a temperature of < -300C, 14.5 ml (23.2 mmol) of n-butyllithium (n-BuLi) (1.6 M in hexane). The mixture is stirred further at this temperature for 30 minutes. It 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 stirring is continued for another hour. This affords a suspension of the monochlorophosphine X1.
With the complex challenges of chemical substances, we look forward to future research findings about 1,1'-Dibromoferrocene
