Article abstract of DOI:10.1039/DT9900001867

Novel copper(II) and nickel(II) complexes of macrocyclic Schiff bases formed from derivatives of N,N'-bis(2-benzoylphenyl)oxamide and 1,2-diaminoethane have been prepared.In one case, separation of atropoisomeric chiral complexes has been achieved by preparative chromatography on SiO2.Quaternization of some of the complexes with an excess of MeI affords chiral complexes possessing a positively charged quaternary ammonium group and polyether podands in addition to a weakly electrophilic metal site.
