The preparation and spectroscopic data of the complexes trans-Cl2Pd(H2NC(CO2R)=C)2 (1) and trans-Cl2Pd(HN=C(CO2R)-CH)2 (6) and of (+)BF4(-) (2) are reported.The reactions of dehydroamino acid esters R(ROC)-C=C(CO2R)NH2 with Na2PdCl4 give 1-imino-3-ketonato chelate complexes cis- (3), of which one representative (3b) has been characterized by X-ray structure analysis.For comparison the structure of the dehydroamino acid derivative OC(Me)C(CO2Et)=C(CO2Et)NH2 (4) has also been determined.Palladium(II) binds the anion of dehydroarmentomycin via the N,O atoms (8).This coordination is also found with (η5-C5H5)(OC)2Mo and allylglycine (9).
