COPPER(II) COMPLEXES WITH MACROCYCLIC LIGANDS DERIVED FROM 1,2-DIAMINOETHANE AND SOME CHLOROCARBONS

摘要

Template condensation of the chlorocarbons carbon tetrachloride, 1,1,2,2-tetrachlorethane or 1,1,2,2-tetrachloroethylene with 1,2-diaminoethane in the presence of copper(II) hydroxide in butanol yields copper complexes of the macrocyclic ligands 1,4,6,9,11,14,16,19,21,24-decaaza-5,5,10,10,15,15,20,20,25,25-decachloro-c yclopentacosane (DDCP) ([Cu-5(DDCP)(H2O)(10)]Cl-10. 4H(2)O), 1,4,7,10-tetraaza-5,6,11,12-tetrachlorocyclododecane (TTCD) ([Cu-2(TTCD)Cl(H2O)(3)]Cl-3) and 1,4,7,10-tetraaza-5,6,11,12,-tetrachlorocyclododeca-5,11-diene (TTDD) ([Cu-2-(TTDD) (H2O)(4)]Cl-4 . 12H(2)O), respectively. the metal-free macrocycles DDCP and TTDD have also been obtained by removing copper(II) ion as metal sulphide from their corresponding complexes. The compounds have been characterized by analytical and spectral studies. [References: 11]
