Synthesis and Structures of New Cyclopalladated Ferrocenylimines

The new complexes, [PdCl{C5H4FeC5H4CHRN=CHC4H3O}(Ph3P)] (R= H, CH3) were synthesized via two novel Schiff bases (C5H5FeC5H4CHRN=CHC4H3O, R= H, CH3) with lithium tetrachloropalladate (Ⅱ), and characterized by IR, elemental analysis, 1H NMR. Complex 5a was further determined by X-ray single crystal diffraction. We found that it contained an intramolecular N→Pd coordination in the compound Sa, and the palladium atom was bound to the unsubstituted Cp ring. The Pd-N, Pd-C (1) and Pd-O bond lengths were 2.121 (3), 2.008 (4) and 2.990 (A), respectively.
