solubility of bimetallic complexes in organic solvents, some new 3,6-bis(2′-pyridyl)pyridazine-based molecules have been synthesised and tested as ligands in platinum(II) organometallic complexes. The reaction of 3,6-bis(2′-pyridyl)-1,2,4,5-tetrazine with terminal acetylenes gives 3,6-bis(2′-pyridyl)-4-substituted pyridazines. Their further reactivity toward (DMSO)2Pt(CH3)2 or (COD)Pt(C6H5)2 (1:1 molecular
为了提高双金属配合物在有机溶剂中的溶解度,已经合成了一些新的基于3,6-双(2'-吡啶基)哒嗪的分子,并作为铂(II)有机金属配合物中的配体进行了测试。3,6-双(2'-吡啶基)-1,2,4,5-四嗪与末端乙炔的反应得到3,6-双(2'-吡啶基)-4-取代的哒嗪。据报道它们对(DMSO)2 Pt(CH 3)2或(COD)Pt(C 6 H 5)2(1:1分子比)的进一步反应性。描述了通过IR,1 H NMR和电子光谱对新合成的化合物进行表征的方法。
