2,9-Disubstituted and 3,8-disubstituted 1,10-phenanthrolines have been converted to the respective 5,6-diamines in three steps. The new heterocycles have been employed in condensation reactions with a protected 1,2-dialkynyl-1,2-dione to afford solubility-improved, acetylenic pyrazinophenanthrolines (pyzphen). In an initial study, the synthetic scope of these novel acetylenic ligands is evaluated.
通过三个步骤,2,9-二取代和 3,8- 二取代的 1,10-菲罗啉被转化为相应的 5,6- 二胺。新杂环在与受保护的 1,2-二炔基-1,2-二酮的缩合反应中得到了溶解度改进的乙炔基吡嗪菲罗啉(pyzphen)。在一项初步研究中,对这些新型乙炔配体的合成范围进行了评估。
