由苯并-15-冠-5经硝化、还原和缩合反应,制备了4＇-(2-羟基苯亚甲基亚氨基)苯并-15-冠-5(L~1H)和4＇,5＇-双(2-羟基苯亚甲基亚氨基)苯并-15-冠-5(L~4H_2)以及它们的取代衍生物L~2H和L~5H_2.在不同温度和不同轴配体存在下,测定了它们的钴(Ⅱ)配合物的氧合常数和ΔH°,ΔS°,并与未冠醚化的类似物CoL_2~3和CoL~6比较,讨论了配体结构和轴配体碱性对配合物的氢分子加合性能的影响.
The 4 ’- (2-hydroxybenzylideneimino) benzo-15-crown-5 (L ~ 1H) and 4’ 5-bis (2-hydroxybenzylideneimino) benzo-15-crown-5 (L ~ 4H_2) and their substituted derivatives L ~ 2H and L ~ 5H_2. The oxygenation constants and ΔH °, ΔS ° of their cobalt (Ⅱ) complexes were determined and compared with the uncoated analogues CoL_2 ~ 3 and CoL ~ 6. The ligand structure and axis Effect of Basicity of Ligand on Hydrogen Adduct Addition of Complexes.
