Abstract

New asymmetrical ligands (H2L) have been synthesized to provide both a bridging and a terminal phenolate to a pair of iron ions in order to mimic the binding of a single terminal tyrosinate at the diiron center of the purple acid phosphatases. H2L1 is 2-[(bis (2- pyridylmethyl) amino) methyl]-6-[((2-pyridylmethyl)(2-phenol) amino) methyl]-4- methylphenol and H2L'1 and H2L2 are obtained by replacing the 2-phenol group by the 5 ...
