  Redox Control of a Ring-Opening Polymerization Catalyst

  摘要：

  The activity of an yttrium alkoxide complex supported by a ferrocene-based ligand was controlled using redox reagents during the ring-opening polymerization of L-lactide. The oxidized complex was characterized by X-ray crystallography and H-1 NMR, XANES, and Mossbauer spectroscopy. Switching in situ between the oxidized and reduced yttrium complexes resulted in a change in the rate of polymerization of L-lactide. Synthesized polymers were analyzed by gel permeation chromatography. Polymerization of trimethylene carbonate was also performed with the reduced and oxidized forms of an indium alkoxide complex. The indium system showed the opposite behavior to that of yttrium, revealing a metal-based dependency on the rate of polymerization.

  Schiff base metal complexes were investigated, where each series was supported by an ancillary ligand incorporating a ferrocene backbone and different N=X functionalities. One ligand is based on an imine, while the other is based on an iminophosphorane group. Cerium(IV), cerium(III), and yttrium(III) alkoxide complexes supported by the two ligands were synthesized. All metal complexes were characterized

  研究了两个系列的席夫碱金属配合物，其中每个系列均由结合了二茂铁骨架和不同N = X官能度的辅助配体支持。一种配体基于亚胺，而另一种配体基于亚氨基膦烷基。合成了由两个配体支撑的铈（IV），铈（III）和钇（III）醇盐配合物。通过循环伏安法表征所有金属络合物。此外，还使用了NMR，Mössbauer，X射线吸收近边缘结构（XANES）和吸收光谱。实验数据表明，铁保持在+2氧化态，而铈（IV）不会与辅助配体发生氧化还原行为。
