It is surprising that no one has considered that coordination might have some effect on the strength of the acid group. It is the intent of this study to fill this gap in the knowledge of amino-acid chemistry.
At about the time this study began on the effect of chelation on the strength of the uncomplexed acid group, the next two higher homologs of these dicarboxylic amino acids became commercially available. It was, therefore, decided that the problem of this research should be expanded to include all four of the acidic amino acids.
The research problem was also defined to include the systematic synthesis of the platinum and palladium (II) complexes of the four available alpha amino dicarboxylic acids, [see PDF]. Platinum and palladium were chosen since in the +2 oxidation state they were known to form only square planar compounds
