Abstract
Six square-planar complexes, [PdL(meso-stien)](ClO4)2 (meso-stien=meso-1,2-diphenyl-1,2-ethanediamine; L=N,N-diethylethylenediamine, N,N-dimethylethylenediamine, 2-methyl-1,2-propanediamine, N2,N2-dimethyl-2-methyl-1,2-propanediamine, N, N-dimethyl-1,3-propanediamine, and (2S)-N1,N1diethyl-1,2-propanediamine), were prepared and optically resolved (or separated in the case of the last named ligand) using diacetyl-d-tartaric anhydride as the resolving agent. Their electronic absorption and CD spectra were measured. A definite additivity has been confirmed between the configurational CD caused by the chiral configuration and the vicinal CD due to the asymmetric carbon atom in the (2S)-N1,N1-diethyl-1,2-propanediamine complex. Absolute configurations of this and the other five complexes have been assigned by examining molecular models and the CD spectra.
