Facile and Selective Conversion of Ethylenediaminetetraacetate to Ethylenediamine-N,N,N'-triacetate on a Cobalt Complex

Article abstract of DOI:10.1246/cl.1993.1009

Ethylenediaminetetraacetatocobaltate(III) is converted to aqua(ethylenediamine-N,N,N'-triacetato)cobalt(III) selectively in a 1 mol dm^-3 K2CO3 aqueous solution at room temperature in the presence of PbO2.This reaction could be a simple and versatile procedure to obtain ed3a-type ligands.
