THE CHEMISTRY OF RHENIUM AND TECHNETIUM. PART II. SCHIFF BASE COMPLEXES WITH POLYFUNCTIONAL AMINO ACIDS

Amino acid Schiff base technetium(V) complexes of salicylaldehyde with l-cysteine, l-serine, l-histidine, l-threonine, l-glutamic acid and l-tryptophan have been prepared by direct reaction and by constituent combination. The amino acid part of the ligands coordinates to the technetium through the carboxylate group, while the other available functional group of the amino acids plays a more minor role as a blocking group or in intramolecular bonding.
