中文摘要 | 利用麥可加成反應由丙烯醯胺與二胺基試劑反應可合成二胺基二醯胺配位子,此種觀位子在水溶液中之質子化常數,及與二價銅和二價鎳錯合物之形成以及錯合物中兩個體胺基的M-O鍵與M-N鍵之鍵轉換反應在相同之條件下,經由電位滴定和光譜法定量研究之,並且對於二價銅和二價鎳錯合物以及它們的去質子狀態的電子吸收光譜加以討論,另外利用卡計方法求出配位子及形成ML2+,M-O鍵到M-N鍵轉換之熱唅量及情之變化,比較其穩定度與熱量變化之關係。 |
英文摘要 | The diamino diamide ligands were synthesized from acrylamide and different diamino reagents by using the Michael addition reaction. The protonation constants of ligands were determined potentiometrically. The formation of copper (II) and nickel (II) complexes and the M-O to M-N bond rearrangements at the two amide sites of these complexes were investigated quantitatively by potentiometric and spectrophotometric techniques under the same conditions. Electronic spectra of the copper (II) and nickel (II) complexes of these ligands and their deprotonated species formed in aqueous solution were measured and the results are discussed. The enthalpy and entropy of the ligands, ML and M -O to M- N bond rearrangements were measured by a calorimetric method to compare the relationship between stability and heat change. |
