使用三个Salen骨架SA1~SA3和四条寡肽P1~P4制备了9个多肽修饰的Salen-Co(II)配合物. 采用肉桂醇的氢肼化反应来评价这些金属配合物的催化活性. 虽然基于骨架SA1的催化剂缺少催化性能, 但是它们的母体配合物1SalenCo和基于骨架SA2SA3的多肽修饰的金属配合物则表现出优秀的催化活性. 这些结果表明多肽对Salen钴金属配合物的催化活性的影响不容忽视, 并且在低温条件下更明显.

Nine peptide-modified Salen-Co(II) complexes based on three Salen ligand frameworks SA1~SA3 and four oligopeptides P1~P4 have been prepared. Their catalytic activities were examined through a model hydrohydrazination of cinnamic alcohol with azodicarboxylate. While peptide-modified Salen-Co(II) complexes derived from SA1 are ineffective, its parent 1SalenCo and those based on SA2 and SA3 are excellent catalyst for this reaction. These results demonstrate that peptide ligands significantly modulate the catalytic activity of SalenCo(II) complexes, particularly at lower temperatures, likely due to hydrogen-bonding interactions.
