Self-assembled coordination thioether silver(I) macrocyclic complexes for homogeneous catalysis
by X-ray diffraction. This alkylaryl thioether ligand (L) formed different macrocyclic complexes by coordination with silver(I) salts depending on the nature of the anion: M2L2 for AgOTf and AgOTFA, M6L4 for AgNO3. A discrete M2L complex was obtained in the presence of bulky PPh3AgOTf. These silver(I) complexes adopted similar structures in solution and in the solid state. As each sulfur atom in the
所述双-邻-thioether 9,10-双[(ø -甲硫基)苯基]蒽合成为顺式阻转异构体,通过X射线衍射所揭示。该烷基芳基硫醚配体(L)通过与银(I)盐配位而形成不同的大环络合物,具体取决于阴离子的性质:AgOTf和AgOTFA为M 2 L 2,AgNO 3为M 6 L 4。在庞大的PPh 3 AgOTf存在下获得了离散的M 2 L复合物。这些银(I)配合物在溶液和固态中采用相似的结构。由于配体中的每个硫原子都是手性的,因此大环L 2 M根据与银阳离子配位的硫原子的构型,获得2为非对映异构体的混合物。两个L 2 ·(AgOTf)2立体异构体的X射线结构突显了它们不同的几何形状。所有银(I)配合物的催化活性在均相条件下,使用0.5-1 mol%的催化负载量进行两次炔烃加成/环异构化反应时均有效。
