Abstract Copper(II) complexes (3a–d and 4a–d) containing tridentate 2,6-bis(benzimidazole-2-yl) pyridine (bzimpy) were synthesized and characterized by 1H-NMR, elemental analysis, IR, UV and mass spectroscopy. These complexes were tested as catalysts in transfer hydrogenation (TH). The effects of wingtip substituents on bzimpy ligand to the TH activity of Cu(II) complexes were investigated. Among the
摘要 合成了含有三齿 2,6-双(苯并咪唑-2-基)吡啶 (bzimpy) 的铜 (II) 配合物 (3a-d 和 4a-d) 并通过 1H-NMR、元素分析、红外、紫外和质谱表征光谱学。这些配合物在转移氢化 (TH) 中作为催化剂进行了测试。研究了翼尖取代基对 bzimpy 配体对 Cu(II) 配合物 TH 活性的影响。在催化剂中,具有空间庞大的 bzimpy 配体的配合物 4d 在该转化中表现出最高的催化活性。图形概要
