Optically active (2-aminomethylferrocenyl)phosphines with the phosphorus chiral center

The reaction of an enantiomeric planar-chiral palladium derivative of dimet hylaminomethylferrocene with PhMePLi in THF at room temperature afforded a 1.5:1.0 mixture of diastereomeric aminophosphines containing the phosphorus asymmetrical center along with a chiral plane. The absolute configuration of the phosphorus atom was determined based on the X-ray diffraction data f or the complex of the minor diastereomer with Pdl(2). The presence of the ( S)-chiral plane in the initial: palladium compound favors the predominant f ormation of the product with. the (S)-configuration of the phosphorus cente r.
