By metal exchange in DMSO (K/sup +/ cation) pK values have been measured for a series of acids which are Ni(II) complexes of Schiff's bases of the amino acids Gly, S-Ala, and S-Val, with S-2-N-(N'-benzylprolyl)aminobenzaldehyde and S-2-N-(N'-benzylprolyl)aminobenzophenone. The amino acid fragment in the studied Ni(II) complexes possesses high acidity close to fluorene but five orders of magnitude greater than for acetophenone and approaching nitroalkanes in acidity.
