Compounds may have at least two structural units, which may be referred to as ligands. Each structural unit includes at least one spacer group and two or more donor groups. Compounds may have two or more iron(III) cations, one or more of which may be a high- spin iron(III) cation or high-spin iron(III) cations, two or more gallium(III) cations, or at least one iron(III) cation, one or more of which may be a high-spin iron(III) cation or high-spin iron(III) cations, and at least one gallium(III) cation, where the iron(III) cation(s) and/or the gallium(III) cation(s) coordinate to the donor groups. The compounds may be self-assembled cages. A composition may include one or more of the compound(s) and a pharmaceutically accepted carrier. Methods of imaging use one or more of the compound(s) and/or one or more of the composition(s).

Utilizing 1,10-phenanthroline-type bifunctional ligands, an efficient Cu-catalyzed intermolecular site-selective remote C–H amination using cyclohexenonederivatives and anilines was realized. The amide group installed on the bifunctional ligand played a key role in stabilizing the N-centered radical generated in situ to realize C–N-directed formation. Meanwhile, a useful catalytic system for site-selective
利用 1,10-菲咯啉型双功能配体,实现了使用环己烯酮衍生物和苯胺的高效铜催化分子间位点选择性远程 C-H 胺化。安装在双功能配体上的酰胺基团在稳定原位产生的 N 中心自由基以实现 C-N 定向形成方面发挥了关键作用。同时,建立了一个有用的催化体系,用于位点选择性分子间远程γ-C-H胺化对氨基苯酚和γ-胺化烯酮。这种使用氧气作为终端氧化剂的经济实用方法温和且环保。
Scandium Ion-Enhanced Oxidative Dimerization and <i>N</i>-Demethylation of <i>N</i>,<i>N</i>-Dimethylanilines by a Non-Heme Iron(IV)-Oxo Complex
dimerization of N,N-dimethylaniline (DMA) occurs with a nonheme iron(IV)-oxocomplex, [FeIV(O)(N4Py)]2+ (N4Py = N,N-bis(2-pyridylmethyl)-N-bis(2-pyridyl)methylamine), to yield the corresponding dimer, tetramethylbenzidine (TMB), in acetonitrile. The rate of the oxidative dimerization of DMA by [FeIV(O)(N4Py)]2+ is markedly enhanced by the presence of scandium triflate, Sc(OTf)3 (OTf = CF3SO3–), when TMB is
