Synthesis and characterization of new Pd(II) complexes of L-ethylphenylalanate.
Complex (S,S)-[Pd{C(6)H(4)(CH(2)CHNH(2)CO(2)CH(2)CH(3))}(mu-Br)](2) (3) was prepared following the method by Vicente and Saura-Llamas (Organometallics 26:2768-2776, 2007), by the reaction of L: -ethylphenylalanate and Pd(OAc)(2) in 1:1 molar ratio under acetonitrile heating conditions and subsequently treating with NaBr. In addition, the cleavage of halogeno-bridge of the complex 3 via nucleophilic attack of some neutral ligands such as triphenylphosphine, pyridine, 2,4,6-trimethylpyridine and piperidine were investigated and the corresponding complexes (S)-[Pd{C(6)H(4)(CH(2)CHNH(2)CO(2)CH(2)CH(3))(Y)(Br)}] (4a-f) were obtained in moderate yields. The six-member orthopalladated complexes were characterized by (1)H-NMR, (31)P-NMR, FT-IR and elemental analysis techniques.
