b) Preparation of L (mixture of diastereomers); To a solution of 5.98 g (23.2 mmol) of (R)-1-dimethylamino-1 -ferrocenylethane in 40 ml of diethyl ether (DE) are added dropwise, at <-10C, 15.5 ml (23.2 mmol) of t-butyllithium (t-BuLi) (1.5 M in pentane). After stirring at the same temperature for 10 minutes, the temperature is allowed to rise to room temperature and the mixture is stirred for another 1.5 hours. This affords a solution of compound X2 which is added via a cannula to the cooled suspension of the monochlorophosphine X1 at a sufficiently slow rate that the temperature does not rise above -300C. After stirring at -300C for a further 10 minutes, the temperature is allowed to rise to 0C and the mixture is stirred at this temperature for another 2 hours. The reaction mixture is admixed with 20 ml of water. The organic phase is removed and dried over sodium sulphate, and the solvent is distilled off under reduced pressure on a rotary evaporator. After chromatographic purification (silica gel 60; eluent = 85:10:5 heptane/ethyl acetate/thethylamine), 11.39 g of the desired product are obtained as a mixture of 2 diastereomers.

Cu(CH3COO)2H2O (52 mg, 0,26 mmol) was dissolved in the smallest possible amount of acetone and treated with an excess of Me6TREN. The mixture was left under vigorous stirring for a couple of hours. During this time, the solution turned from blue to green. After evaporation of the solvents, the green product was redisolved in acetone and an excess of KPF6 (dissolved in acetoneas well) was added. The white solid CH3COOK formed on the bottom of the flask and it was filtered off. The light blue solution was dried under vacuum and the solid dissolved in dichloromethanein order to eliminate the excess of KPF6. After filtration of the solid residue, the solution was reduced in volume and the pure product 4 precipitated upon addition of diethylether. Crystals suitable for XRD were grown at low temperature by slow diffusion of diethyl ether into a dichloromethane solution of 4. Yield: 27%; Anal.
