✦ Synopsis

The complexes formed between palladium(II) and a series of polymers and model molecules derived from alanine, aspartic acid and glutamic acid have been investigated by electronic absorption and circular dichroism. It has been concluded that 1 N and 2 N optically active species are formed with participation of the carboxylate and the amide group (five membered chelate ring). In most cases the 1 N complex is the major species, except for the polymer and model molecule derived from alanine where the 2 N complex can form at high pH. With the polymers, the complexes become optically inactive at high pH when the carboxylate-palladium bonds are hydrolyzed.
