Metal template reactions. XVIII. Macrocyclic metal complexes derived from 2,6-diacetylpyridine and some primary diamines with additional nitrogen donor atoms

Abstract

Macrocyclic nickel(II), copper(II) and cobalt(II) complexes (6), (8), (10), (12) and (14) have been prepared from 2,6-diacetylpyridine, the appropriate metal salt and the primary diamines 2,2'-(iminodimethylene)bisaniline (5), azobenzene-2,2'-diamine (7), 2,2'-iminobisaniline (9), 2-amino- N-(2'-aminopheny1)benzamide (11) and 2-amino-N-(2'-aminobenzoy1)benzamide (13) respectively. The primary diamines 2,2'-diaminooxanilide (15) and N,N'-(2'-phenylene)bis(2'-aminobenzamide) (16) could not be incorporated into macrocyclic ligands by similar techniques.
