A novel tripodal hexadentate ligand, consisting of three catechol units, three isobutenyl ether arms, and one aromatic core, was synthesized through four steps, in which the Claisen rearrangement was included as the key step. The hexadentate ligand formed a 1:1 complex with iron(III) trichloride hexahydrate with an equilibrium constant (conditional) of 6.3 × 104 M−1 in acetonitrile in the presence
通过四个步骤合成了由三个邻苯二酚单元,三个异丁烯基醚臂和一个芳族核组成的新型三足六齿配体,其中包括克莱森重排作为关键步骤。在2,4,6-三甲基吡啶存在下,六齿配体与六水合三氯化铁(III)六价铁形成1:1络合物,平衡常数(条件)为6.3×10 4 M -1。
