  Tellurated heterocycles, 2-[(2-thienyltelluro)methyl]tetrahydrofuran (L1) and [(2-thienyltelluro)methyl]tetrahydro-2H-pyran (L2): Synthesis and complexation reactions with Pd(II), Pt(II), Hg(II), Ru(II) and Cu(I)

  摘要：

  2-Thienyllithium (ThLi) reacts with elemental Te to give ThTeLi which on reaction with tetrahydrofurfurylchloride and 2-(bromomethyl) tetrahydro-2H-pyran at -78 degrees C results in L-1 and L-2. Their complexes [PdCl2(L-1)(2)] (1), [PtCl2(L-1)(2)](2), [HgBr2(L-1)(2)](3), [Ru(p-cym-ene)Cl-2(L-1)] (4), [CuBr(L-1)] (5), [PdCl2(L-2)(2)](6), [PtCl2(L-2)(2)](7), [HgBr2(L-2)(2)](8) and [Ru(p-cymene)Cl-2(L-2)] (9). Both the ligands and all nine complexes have characteristic H-1 and C-13 NMR spectra which reveal that in most of the complexes the two ligands L-1 and L-2 coordinate through Te only. This is corroborated by single crystal structures of 4 and 6. The 4 is a half sandwich compound, in which coligands of p-cymene are Cl and L-1 (monodentate coordinated through Te). The Ru-Te bond length is 2.6340(angstrom) A. In the 6 Pd has nearly square planar geometry and molecules of ligand L-2 are cis to each other, which is something rare with the monodentate telluride ligands. The Pd-Te bond lengths are 2.538(2) and 2.517(2) angstrom. The crystal structure of 6 also shows presence of secondary (TeCl)-Cl-. . . interactions in the crystal lattice. The Pd-Pd distance in 6 becomes 3.188(3) angstrom, less than 3.26 angstrom (sum of vander Waal's radii). The ligation of L-1 and L-2 is compared with those of related ligands. (c) 2006 Elsevier B.V.
