two-coordinated Ag(I) complexes. Reaction of AgX with 1 equiv of chiral N4-ligands 5, 7, 8 and 10 gives the chiral, binuclear double helicate Ag(I) complexes, while chiral mono-nuclear single helicate Ag(I) complexes are obtained with N4-ligands 6 and 9. Treatment of either N3-ligand 1 or N4-ligand 9 or 10 with 1 equiv of CuX2 (X = Cl, ClO4) gives the mono-ligated Cu(II) complexes. All the complexes have been
从AgX(X = NO 3,PF 6,OTf)或CuX 2(X = Cl,ClO 4)与手性联芳基N的反应制备了一系列手性Ag(I)和Cu(II)配合物-配体。配体的刚性在Ag(I)配合物的形成中起着重要作用。例如,治疗的手性Ñ 3 -ligands 1 - 3与卤化银的一半当量(X = NO 3,PF 6,光学传递函数),得到手性二连接四配位的Ag(I)配合物,而配体4,得到两个配位的Ag(I)配合物。AgX与1当量的手性N 4配体5的反应,7,8和10给出了手性,双核双helicate银(I)络合物,而手性单核单helicate银(I)配合物是用N得到4 -ligands 6和9。是N-的治疗3 -配体1或N 4 -配体9或10用1个当量的CuX的2(X =氯,CLO 4)给出单连接的Cu(II)配合物。所有配合物均已通过各种光谱技术和元素分析进行了表征。X射线衍射分析进一步证实了
