摘要
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。
Redox-Active Tin(IV) Complexes Based on Sterically Hindered Catecholate Ligands
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.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
