| 摘 要： | 手性膦（Ｌ）配位的钯化合物ＰｄＣｌ２Ｌ２，Ｌ＝２－ＭＢＰＡ（１）；Ｌ＝３－ＭＢＰＡ（２），在ＤＭＦ中的循环伏安法电化学研究表明，二个化合物的氧还性质相近，与膦在Ｄ－醣上的碳取代位置无关．化合物的氧还反应有一个还原峰和两个氧化峰．比较化合物（２）在乙氰和ＤＭＦ中的ＣＶ图，显示两个氧化峰系由溶剂配位后的还原产物［ＰｄＬ２（Ｓｏｌｖｅｎｔ）２］１－氧化而得

| Abstract: | Complexes PdCl 2L 2 with chiral phosphines L=2 MBPA(1);L=3 MBPA(2),showed very similar CV curves in DMF with one reduction and two oxidation waves, indicationg the redox behaviors of (1)and (2) are similar and irrespective of the substitution positions of the phosphorus atoms on the D sugar rings. The reaction processes are shown by the fact that the CV curve of (2)in the less polar solvent MeCN which coordinates to the complex slower than DMF, showed only an irreversible reduction wave, while the two oxidation waves are caused by solvent coordinated species. |
