Abstract
In this study, a novel (E,E)-dioxim containing a diazatetrathiadioxa macrobicyclic moieties (19E, 20E)-6,7,14,15,18,21,24,25-oktahydro-13,26-(ethanothioethano-thioethano)dibenzo [14,15:8,9]-[1,4,10,13,7,16]dioxadithiadiazacyclooctadecino[2,3-g] quinoxaline- 19,20,27,34-tetrone 19,20-dioxime (H 2 L) has been synthesized by reacting cyanogen-di-N-oxide with 2,3-diamino-6,7,14,15,22,23-hexahydro-8,21-(ethanothioethanothioethano)tribenzo[b,h,n][1,4,10, 13,7,16]dioxadithiadiazacyclooctadecine-25,32-dione ( 8 ), which was prepared by the reduction of 2,3-dinitro-6,7,14,15,22,23-hexahydro-8,21-(ethanothioethanothioethano)-tribenzo[b,h,n] [1,4,10,13,7,16]dioxodithiadiazacyclooctadecine-25,32dione ( 7 ). The macrobicyclic ( 7 ) was synthesized by the condensation reaction of compound ( 5 ) with compound ( 6 ) in the presence of the Na 2 CO 3 under an argon atmosphere in the refluxing acetonitrile. Mononuclear complex ( 11 ) with metal:ligand ratio 1:2 of this ligand has been synthesized by reacting the vic-dioxime (H 2 L) with NiCl 2 .6H 2 O. The new compounds were characterized by a combination of elemental analysis, 1 H- and 13 C-NMR, IR and MS spectral data.
