Syntheses of Co(II), Ni(II), Cu(II), Fe(III) and Cr(III) Complexes ofOrtho-Substituted Benzenes: Model Complexes of Natural Organic Matter

摘要

This paper describes the syntheses of several model complexes for the metal complexes formed between aquatic or soil organic matter and metal ions. Based on functional group analyses of the natural organic matter, we choseortho-substituted benzenes as chelating agents. They are salicylaldehyde, 2#x2032;-hydroxyaceto-phenone, methylsalicylate, and 2-methoxyphenol. A variety of cobalt(II), nickel(II), copper(II), iron(III), and chromium(III) complexes were prepared.
