It is a common heterocyclic compound, the iron-catalyst compound, 1,1′-Dibromoferrocene, cas is 1293-65-8 its synthesis route is as follows.
To a solution of 103 g (0.3 mol) of 1 ,1 ‘-dibromoferrocene in 300 ml of THF are added dropwise, at a temperature of < -300C, 120 ml (0.3 mol) of n-BuLi (2.5 M in hexane). The mixture is stirred at this temperature for a further 1.5 hour. The mixture is then cooled to -500C, and 66.2 ml (0.3 mol) of dicyclohexylphosphine chloride are added dropwise sufficiently slowly that the temperature does not rise above -45C. After stirring for a further 10 minutes, the temperature is allowed to rise to room temperature and the mixture is stirred for another hour. After 150 ml of water have been added, the reaction mixture is extracted by shaking with hexane. The organic phases are dried over sodium sulphate and the solvent is distilled off under reduced pressure on a rotary evaporator. The residue is crystallized in ethanol. The product A2 is obtained with a yield of 84% (yellow solid).31P NMR (121.5 MHz, C6D6): delta -8.3 (s); 1H NMR (300 MHz, C6D6): delta 4.41 (m, 2H), 4.26 (m, 2H), 4.23 (m, 2H), 3.97 (m, 2H), 1.20-2.11 (m, 22H).
