Mild template synthesis of copper(II)-containing macrocyclic compounds in the Cu~(II)-1,2-diaminoethanedithione-1,2-ethanedione-1,2 and Cu~(II)-1,2-diamino-ethanedithione-1,2-butanedione-2,3 triple systems into Cu2[Fe(CN)6]-gelatin-immobilized matrix

摘要

The complexing processes in the Cu~(II)-1,2-diaminoethanedithione-1,2-ethanedione-1,2 and Cu~(II)-1,2-diamino-ethanedithione-1,2-butanedione-2,3 triple systems occuring in the copper(II)hexacyanoferrate(II)gelatin-immobilized matrix in contact with aqueous alkaline solutions(pH~12)containing 1,2-diaminoethanedithione-1,2 and ethanedione-1,2 or butanedione-1,2 under room temperature,and between MCl2,1,2-diaminoethanedithione-1,2 and ethanedione-1,2 or butanedione-1,2 in the ethanol solutions,upon heating up to ~80 °C,have been studied.In both systems indicated,template synthesis occurs in the gelatin-immobililized matrix but does not occur in the ethanol solution.As a result of template synthesis,macrocyclic Cu~(II)chelates with 2,7-dithio-3,6-diazaoctadien-3,5-dithioa-mide-1,8 and its 4,5-dimethylsubstituted derivative are formed in the gelatin-immobililized matrix.1,2-diamino-ethanedithione-1,2 and ethanedione-1,2 or butanedione-2,3 are the ligand synthons in the processes indicated.
