Abstract

The synthesis of crown ether derivatives containing the dipyridino subunit is described. Direct nucleophilic displacement by the glycolates of di-, tri-, tetra-, penta-, and hexaethylene glycol on 6, 6'-bis (chloromethy1)-2, 2'-dipyridine resulted in an extensive series of macrocycles; the addition of Co (II), Cu (II), Zn (II), and Pd (1I) salts to the 1: l-and 2: 2- macrocycles generated the corresponding complexes. X-ray crystallography confirmed ...
