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

Abstract

Two pairs of novel diastereomeric cyclopalladated ferrocenylimines ( S p, S C)- 3 and ( R p, S C)- 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 ( S p, S C)- 3a and ( R p, S C)- 4b have been determined by single-crystal X-ray diffraction.
