The preparation of a new type of N2S2 tetradentate ligand 3 with the bis(hydrazonothioamide) structure is reported in this paper. The key step in this synthesis is the condensation of the dihydrazine 7 with an α-ketoester. Ligand 1,2-bis[(2-dimethylamino-2-thioxo-1-phenylethylidene)hydrazino]ethane}
3 was obtained in 6 steps from secondary amine. This ligand is then used in the preparation of a nickel(II) complex 4 and the mesomeric forms of metallic complex NiN2S2 are discussed.
本文报告了一种新型N2S2四齿配体3的制备,该配体具有双(肼硫酰胺)结构。合成中的关键步骤是二肼7与α-酮酸酯的缩合。配体1,2-双[(2-二甲基氨基-2-硫代-1-苯基乙烯基)肼基]乙烷} 3是通过6个步骤从次级胺获得的。随后,该配体用于制备镍(II)络合物4,并讨论了金属络合物NiN2S2的共振形式。
