Abstract The Cu(II) complexes bearing bisoxazolines, tridentate pincer pybox and terpyridine ligands have been synthesized and fully characterized. The molecular structures of coppercomplexes 1a and 1c were confirmed by single-crystal X-ray diffraction methods. These coppercomplexes highly catalyzed nitro compounds reduction to aniline and its derivatives in the presence of NaBH4 reducing agent in
摘要 已经合成并充分表征了带有双恶唑啉、三齿钳状pybox和三联吡啶配体的Cu(II)配合物。铜配合物 1a 和 1c 的分子结构由单晶 X 射线衍射方法证实。这些铜配合物在水溶剂中存在 NaBH4 还原剂的情况下高度催化硝基化合物还原为苯胺及其衍生物。配合物1e是还原硝基化合物的有效催化剂,具有广泛的官能团底物范围和脂肪族硝基化合物。
