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 5a, and the palladium atom was bound to the unsubstituted Cp ring. The Pd-N, Pd-C （I） and Pd-O bond lengths were 2.121 （3）, 2.008 （4） and 2.990 ）A, respectively.

A variety of 2-arylnaphtho[ 1,2-d]oxazole derivatives were efficiently synthesized in moderate to high yields by the reaction of aromatic aldehydes with 1-amino-2-naphthol derivatives in the presence of triethylamine in refluxing ethanol in air. Seven new 2-arylnaphtho[1,2-d]oxazole derivatives were obtained and characterized by the spectral data and elemental analysis. In addition, the X-ray crystal structures of 2-[4-（N,N-dimethylamino）phenyl]naphtho[ 1,2-d] oxzole （3d） and 1, 1＇-bis（naphtho[ 1,2-d]oxazol-2-yl）ferrocene （3n） have been determined.
The novel chiral cyclopalladated compound 2 was synthesized from the reaction of L-valinol derived ferrocenylaldimine 1 with Li2PdCl4/NaOAc followed by treatment with triphenylphosphine.2 was characterized by elemental analysis,ESI-MS,IR,（）1H NMR,specific rotation and singlecrystal X-ray diffraction.The crystal of 2 contains two diastereoners with different planar chirality.It is monocline,space group P21 with Mr:787.23,a=1.0239（2）nm,b=3.2439（7）nm,c=1.0680（2）nm,α=γ=90°,β=90.12（3）°,V=3.5473（12）nm3,Z=4,Dc=1.474g/cm3,F（000）=1600.The final R1=0.0455,wR2=0.0951.X-ray analysis also reveals that the compound 2 has a one-dimensional chain structure.
