synthesis of two types of bis-8-hydroxyquinolines, prepared via either an imination or a Suzuki-Miyaura coupling approach, as well as their analysis is discussed. Imination was pursued through the condensation of quinolinecarbaldehydes with diamines or aminoquinolines with dialdehydes, and the Suzuki-Miyaura coupling reactions were evaluated using a bromoquinoline substrate and diboronic acids.
Bis-8-羟基喹啉代表了重要的但尚未开发的一类潜在的配体,用于制备各种配位聚合物,可用于多种应用中。在这项工作中,讨论了通过酰亚胺化或铃木-宫浦偶联方法制备的两种类型的双8-羟基喹啉的合成及其分析。通过喹啉甲醛与二胺的缩合或氨基喹啉与二醛的缩合来进行胺化,并使用溴喹啉底物和二硼酸评估Suzuki-Miyaura偶联反应。
