Resolution of a cyclopalladated ferrocenylketimine

The cyclopalladated ferrocenylketimine, [{Pd[(eta(5)-C5H5)Fe{eta(5)-C5H3C(C H3)=N(C6H4CH3-4)}](mu-Cl)}(2)] 1 was resolved into optically active diaster eomers by using (S)-leucine as chiral auxiliary. The new optically active ( S)-leucinato complexes of Pd-II containing ferrocenylketimine could be conv erted into optically active dimers with the same absolute configurations in the ferrocene moiety. The structure of the chiral dimer (R-p,R-p)-1 was de termined by X-ray diffraction, on the basis of which the absolute configura tions of all the optically active compounds studied were ascertained.
