Synthesis and structures of novel diastereomeric cyclopalladated ferrocenylimines derived from chiral β-amino alcohols

Two pairs of novel diastereomeric cyclopalladated ferrocenylimines (Sp, SC)-3 and (Rp, SC)-4 with both planar and central chirality have been synthesized starting from inexpensive and readily available chiral β-amino alcohols. The two pairs of diastereomers were characterized by elemental analysis, IR, 1H NMR and specific rotations. Furthermore, the structures and absolute configurations of complexes (Sp, SC)-3a and (Rp, SC)-4b have been determined by single-crystal X-ray diffraction.
