The synthesis of a new vic-dioxime, containing eighteen membered macrocyclic group and investigation of its complex formation

The Synthesis of A New wc-Dioxime, Containing Eighteen Membered Macrocyclic Group and Investigation of Its Complex Formation In this work, (E,E)-dioxime, containing a new macrocyclic group and its nickel (II) complex were synthesized. 6,7-Dinitro-l,12-bis(monoaza[18]crown-6)-benzo[f]-4,9-dioxa- 1,12-diaza-decane (7) was prepared by the reaction of monoaza[18]crown-6 with 1,2- dinitro-4,5-bis(2-iyodoethoxy)benzene. The reduction of this compound has produced the diamine compound (8). A (E,E)-dioxime (9) was synthesized by the reaction of the aromatic diamine compound with cyanogen-di-N-oxide. Bis(dioximato)nickel(II) (10) complex was prepared by the reaction of the dioxime with nickel(II). The structures of the synthesized compounds were identified by using IR, 13C-NMR, ^-NMR, and MS spectrometers. Key words: (E,E)-Dioxime, Transition Metal Complexes, Macrocyclic Compounds, Organometallic Compounds, Crown Ethers, Chelates. VII
