Abstract
|
|
|
|
Novel palladium (Ⅱ) complexes, [Pd((ieaa)2-en)] and [PdCl((ieaa)-l-pn)] ((ieaa)2-en and (ieaa)-l-pn denote N,N'-ethylenebis(isonitrosoethylacetoacetate imine) and l-N-(2-aminopropyl)-isonitrosoethylacetoacetate imine, respectively), have been prepared. The palladium (Ⅱ) complexes were characterized on the bases of the electronic absorption, circular dichroism (CD), 13C NMR, infrared, and Raman spectra. The reaction of palladium(Ⅱ) cliloride and isonitrosoethylacetoacetate (ieaa) with methylenediamine gives an (icaa)2-en type Schiff base, while similar reaction using l-propylenediamine instead of ethylenediamine gives an (ieaa)-l-pn type Schiff base. The difference in formation is discussed from the stereochemical viewpoint of the diamine employed.
