【摘要】 合成并表征了互为立体异构的四氮杂大环多胺配体及其铜(Ⅱ)配合物。在B rij35胶束溶液中,比较研究了配合物催化羧酸酯(2-吡啶甲酸对硝基苯酚酯PNPP)水解的动力学,探讨了导致其催化活性差异的可能原因,提出了可能的催化反应的机理。更多还原

【Abstract】 Two Cu(Ⅱ) complexes of two stereomeric tetraaza macrocyclic polyamine ligands were synthesized and characterized.In the presence of Brij35,the comparative kinetic investigation of the hydrolysis of p-nitrophenyl picolinate(PNPP) catalyzed by two macrocyclic polyamine complexes at 30℃ were reported.The possible reasons for the difference in catalytic activities of two complexes for the hydrolysis of p-nitrophenyl picolinate(PNPP) were discussed in detail and the catalytic mechanisms were proposed.更多还原
