  Stereoselective isomerization of chiral cobalt(III) complexes

  摘要：

  The isomerization reactions among the geometrical isomers of chiral complexes, [Co(edma)2]+, [Co(ida)(edma)], and [Co(mida)(edma)], have been studied in a weakly basic aqueous solution. Some of the optical active isomers exhibited stereoselective isomerization without the loss of optical activity. It was suggested that the isomerization of the isomer with facially or meridionally chelated-ligands proceeded through the deprotonated five-coordinated intermediate formed by Co-O bond-rupture in the conjugate-base form.

  Four geometrical isomers of [Co(mida)(edma)] were prepared in the first time and their structures were determined on the basis of their visible and UV absorption spectral data. Three of the isomers were optically resolved by the use of a column containing QAE-Sephadex of the Sb2(d-tart)22− form. Absolute configurations of the facially chelated isomers of [Co(mida)(edma)] were determined by measuring

  首次制备了[Co(mida)(edma)]的四种几何异构体，并根据其可见光和紫外吸收光谱数据确定了它们的结构。使用含有 Sb2(d-tart)22- 形式的 QAE-Sephadex 的色谱柱对三种异构体进行了光学拆分。[Co(mida)(edma)] 的表面螯合异构体的绝对构型是通过测量光学拆分异构体的 1H NMR 光谱来确定的，该异构体具有不对称的含碳 edma（从立体定向氘化的 (-)543CD C2-trans (O)-[Co(edma)2]2+)。[Co(ida)(edma)] 的表面螯合异构体的绝对构型是根据它们的 CD 光谱数据确定的。
