Relationship between electronic structure and reactivity of various high-valent metal complexes

制备了一系列单电子氧化的金属（II）Salen型配合物，以比较5-和6-元螯合骨架之间的电子结构。二胺骨架的螯合环大小的差异给出了不同的电子结构的氧化的Cu（II）络合物，5元螯合物被分配到一个Cu（III）的基态，而6元螯合物是一个Cu（II）-苯氧基自由基。这些氧化络合物的反应性的调查表明，Cu（II）-苯氧基自由基的反应速率是最快的系列氧化物种。

A series of one-electron oxidized metal(II) salen-type complexes were prepared allowing for a comparison of the electronic structure between 5- and 6-membered chelate backbone. The chelate ring-size difference of the diamine backbone gave different electronic structure of the oxidized Cu(II) complex, the 5-membered chelate complex was assigned to a Cu(III) ground state, while the 6-membered chelate complex was a Cu(II)-phenoxyl radical. Investigation of the reactivity of these oxidized complex revealed that reaction rate of the Cu(II)-phenoxyl radical was fastest in the series of oxidized species.
