  Organosilicon backbone containing pyridyl/quinolyl ligands: Synthesis, complexation reactions and single crystal structures of metallamacrocyclic Pd(II) and Cu(II) complexes

  摘要：

  Organosilicon backbone containing ligands 1,2-bis(dimethyl(2-pyridyl)silyl)ethane (L-1) and 1,2-bis(dimethyl(3-quinolyl)silyl) ethane (L) have been synthesized by treating 2-bromopyridine and 3-bromoquinoline with n-butyllithium and reacting the resulting lithiated lproducts with 1,2-bis(chlorodimethylsilyl)ethane. The ligation of L-1 and L-2 with Pd(II), Ag(I) and Cu(II) has been investigated. The single crystal structures of L-2, [Pd(L-1)Cl-2] (1), [Cu(L-1)Br-2](3) and [PdCl2(L-2)](2) (4) have been solved. All the three complexes are metallamacrocyclic in nature. The last one is 22-membered and the first example which has ligands containing organosilicon backbone. The geometry of Pd as well as Cu is very close to square planar. The Pd-N, Pd-Cl, Cu-N and Cu-Br bond distances (2.010(1)-2.027(3), 2.3063(10)-2.3114(4), 2.004(4)-2.018(5) and 2.4137(10)-2.4172(10) angstrom) are very close to sum of covalent radii, indicating strong ligation of L-1 and L-2 with the metal ions.
