Example B18: Reaction schemeX24 ml (10 mmol) of n-BuLi (2.5 M in hexane) are added dropwise to a solution of 3.44 g (10 mmol) of 1 ,1 ‘-dibromoferrocene in 10 ml of tetrahydrofuran (THF) at a temperature of < -30C. The mixture is stirred at this temperature for a further 1.5 hours. 2.21 ml (10 mmol) of dicyclohexylphosphine chloride are then added dropwise at such a rate that the temperature does not exceed -20C. After stirring the mixture for a further 10 minutes, the temperature is allowed to rise to room temperature and the mixture is stirred for another one hour. It is cooled back down to 30C and 4.4 ml (11 mmol) of n-BuLi (2.5 M in hexane) are added dropwise. The mixture is subsequently stirred at -10C for 30 minutes. The reaction mixture is then cooled to -78C and 1.49 ml (11 mmol) of dichlorophenylphosphine are added. The mixture is stirred at -78C for 20 minutes and then at room temperature for a further one hour. This gives a reaction mixture comprising the monochlorodiphosphine X6. In a second vessel, 8.5 ml (11 mmol) of S-BuLi (1.3 M in cyclohexane) are added dropwise to a solution of 2.57 g (10 mmol) of (R)-1-dimethylamino-1-ferrocenylethane in 15 ml of diethyl ether at <-10C. After stirring the mixture at the same temperature for 10 minutes, the temperature is allowed to rise to 0C and the mixture is stirred for another 1.5 hours. This reaction solution is subsequently added by means of a cannula to the reaction mixture comprising the monochlorodiphosphine X6 which has been cooled to -10C. After the addition, the mixture is stirred at room temperature for another 2 hours. After addition of 10 ml of water, the reaction mixture is extracted, the organic phase is dried over sodium sulphate and the solvent is distilled off under reduced pressure on a rotary evaporator. The residue is heated at 140C for one hour. Column chromatography (silica gel 60; eluent: hexane/ethyl acetate 4:1 ) gives the compound of the formula (B1 ) in a yield of 47%. 31P- and 1H-NMR of the product are identical with those of Example B1.; Example B19: Reaction schemeReaction mixture 1 : 4 ml (10 mmol) of n-BuLi (2.5 M in hexane) are added dropwise to a solution of 3.44 g (10 mmol) of 1 ,1 '-dibromoferrocene in 10 ml of tetrahydrofuran (THF) at a temperature of < -30C. The mixture is stirred at this temperature for a further 30 minutes. It is then cooled to -78C and 1.36 ml (10 mmol) of phenyldichlorophosphine are added. After stirring the mixture for a further 10 minutes, the temperature is allowed to rise to room temperature and the mixture is stirred for another one hour.Reaction mixture 2: In a second vessel, 8.0 ml (10.4 mmol) of S-BuLi (1.3 M in cyclohexane) are added dropwise to a solution of 2.57 g (10 mmol) of (R)-1-dimethylamino-1-ferrocenyl- ethane in 15 ml of diethyl ether at <-10C. After stirring the mixture at the same temperature for 10 minutes, the temperature is allowed to rise to 0C and the mixture is stirred for another 1.5 hours.The reaction mixture 1 is slowly added to the reaction mixture 2 at a temperature below -10C. The mixture is subsequently stirred at room temperature for 1.5 hours. At a temperature in the range from -78C to -50C, 8 ml (10.4 mmol) of S-BuLi (1.3 M in cyclohexane) are then added dropwise. After stirring the mixture at -78C for 20 minutes, the temperature is allowed to rise to 0C and the mixture is stirred for a further 30 minutes before 2.21 ml (10 mmol) of chloro- dicyclohexylphosphine are added at -20C. The mixture is stirred at 20C for another 20 minutes and finally at room temperature for another 1.5 hours. The work-up and thermal epimerization are carried out in a manner analogous to that described in Example B18. The compound of the formula (B1 ) is obtained in a yield of 31 %. 31P- and 1H-NMR of the product are identical with those of Example B1.; Example B20:8.5 ml (11 mmol) of S-BuLi (1.3 M in cyclohexane) are added dropwise to a solution of 2.83 g (1 1 mmol) of (R)-1 -dimethylamino-1 -ferrocenylethane in 15 ml of diethyl ether at <-10C. The cooling is then removed and the mixture is stirred at room temperature for another 2 hours. After cooling to -10C, 2.92 g (10 mmol) of the compound A3 are added and the mixture is stirred at this temperature for a further 30 minutes. The temperature is allowed to rise to room temperature and the mixture is stirred for another one hour. After addition of 10 ml of 1 N NaOH, the reaction mixture is extracted, the organic phase is dried over sodium sulphate and the solvent is distilled off under reduced pressure on a rotary evaporator. A 1H-NMR of the residue shows that the reaction is very stereoselective and gives virtually exclusively the desired diastereomer (RC,SFC, Sp)-I -[2-(1 -dimethylaminoethyl)ferrocen-1 -yl]phenylphosphino- 1 '-dicyclohexylphosphinoferrocene. After chromatography (silica gel 60; eluent = hexane/ethyl acetate 4:1 ), this product is obtained in a yield of 37%. 31P- and 1H-NMR of the produ…
