Abstract

The oxidative addition of sterically hindered 3,6-dicyclohexyl-o-benzoquinone (L¹), 3,5-di-tert-octyl-o-benzoquinone (L²), 4-tert-octyl-o-benzoquinone (L³), and 3,5-bis(2-phenylpropyl)-o-benzoquinone (L⁴) to tin(II) chloride in THF affords the corresponding tin(IV) catecholate complexes with the general formula RCatSnCl₂·2THF, where Cat is the catecholate fragment; and R is 3,6-с-Hex (I), 3,5-tert-Oct (II), 4-tert-Oct (III), and 3,5-C(Me)₂Ph (IV), regardless of the molar ratio of the starting reactants. The molecular structures of substituted o-benzoquinone L⁴ and complexes I and III in the crystalline form are determined by X-ray diffraction (XRD) (CIF files CCDC nos. 2259370 (L⁴), 2259371 (I), and 2259372 (III)). The oxidation–reduction properties of synthesized compounds I–IV are studied by cyclic voltammetry.

基于立体受阻邻苯二酚配体的氧化还原活性锡（IV）配合物

摘要将立体受阻的 3,6-二环己基邻苯醌（L1）、3,5-二叔辛基邻苯醌（L2）、4-叔辛基邻苯醌（L3）和 3、在四氢呋喃中将 5-双（2-苯基丙基）-邻苯醌（L4）与氯化锡（II）反应，可得到相应的邻苯二酚锡（IV）配合物，通式为 RCatSnCl2-2THF，其中 Cat 为邻苯二酚片段；和 R 是 3,6-с-Hex (I)、3,5-叔-Oct (II)、4-叔-Oct (III) 和 3,5-C(Me)2Ph (IV)，与起始反应物的摩尔比无关。通过 X 射线衍射 (XRD)（CIF 文件 CCDC 编号：2259370 (L4)、2259371 (I) 和 2259372 (III)）确定了晶体状取代邻苯醌 L4 和配合物 I 和 III 的分子结构。通过循环伏安法研究了合成化合物 I-IV 的氧化还原特性。
