Facile Access to Tetravalent Cerium Compounds: One-Electron Oxidation Using Iodine(III) Reagents

Readily accessible and easy-to-use phenyliodine(III) dichloride, PhICl2, has been established as an innovative and superior reagent for the one-electron oxidation of cerium(III) complexes, comprising amide, amidinate, and cyclopentadienyl derivatives. Its use allowed the successful synthesis and structural characterization of the first members of three new classes of chloro-functionalized (organo)cerium(IV) compounds, including the long sought-after Cp3CeCl.

易于获取且操作简便的二氯(III)苯基碘（phenyliodine(III) dichloride，缩写PhICl2），已被证实为适用于酰胺、脒基及环戊二烯基衍生物类三价铈配合物单电子氧化的创新性优异试剂。借助该试剂，研究人员成功合成并完成了三类全新氯官能化（有机）四价铈化合物的首例成员的结构表征，其中包括长期以来备受学界关注的三(环戊二烯基)氯化铈(IV)（Cp3CeCl）。
