  Synthesis and spectroscopic studies of palladium and platinum complexes of methylene-backboned dithio-, diseleno- and ditelluro-ether ligands, RECH2ER (R = Me or Ph; E = S, Se or Te)

  摘要：

  The complexes [ML2Cl2] (M = Pd or Pt; L = PhSCH2SPh, MeSCHSMe, PhSeCH2SePh or MeSeCH2SeMe), which are square planar with monodentate sulfur or selenium ligands, have been prepared. In the solid state, on the basis of IR and Raman data, the palladium complexes are trans and the platinum cis, whilst in solution multinuclear NMR spectroscopy (H-1, Pt-195-{H-1}, and Se-77-{H-1}) reveal that both cis and trans isomers and meso and DL enantiomers are present, the isomer populations varying with L and M in a systematic way. The complexes [MLCl2] are stable in solution for L = PhSCH2SPh, but the other complexes lose L to precipitate polymeric [(MLCl2)n] complexes. The ditelluroethers, MeTeCH2TeMe and PhTeCH2TePh, form only the latter type of complex. The crystal structure of trans-[Pd(PhSCH2SPh)2Cl2] has been determined and contains a trans square-planar palladium atom with one co-ordinated and one free sulfur atom associated with each dithioether ligand [Pd-Cl 2.292(l) and Pd-S 2.329(l) angstrom].

  corresponding dimethyl(telluroether)Pt-II complexes do not form under similar reaction conditions. The distorted octahedral [PtMe3I(L)] [L=o-C6H4(CH2SeMe)(2), [8]aneSe2, [16]aneSe(4) or MeC(CH2SeMe)(3)] form as stable complexes in good yield from reaction of PtMe3I with L in refluxing CHCl3 and have been characterised similarly. These all show bidentate selenoether coordination, with fast pyramidal inversion

  Methods of synthesis of compounds MeY(CH2Y)(n) Me (Y=S, Se, Te; n = 1-3) containing several identical or different chalcogen atoms are suggested. The methods are based on the reactions of dichloromethane with elemental chalcogens (Y2-) and dimethyl dichalcogenides (MeY-) activated in the system hydrazine hydrate-alkali. The effect of the chalcogen on the reactivity toward dichloromethane is qualitatively assessed. With elemental tellurium in the system hydrazine hydrate-alkali, reduction of one chlorine atom in dichloromethane and formation of methyltellanyl derivatives are observed.

  Homoleptic copper(I) and silver(I) complexes [M(n)(L-L)(2n)](BF4)(n) (M = Cu or Ag; L-L = MeECH(2)EMe; E = S, Se or Te) have been prepared and characterized by analysis, FAB mass spectrometry, and IR and multinuclear NMR spectroscopy (H-1, Se-77, Te-125, Cu-63 and Ag-109). The single-crystal X-ray structures of [Cu-n(MeSeCH(2)SeMe)(2n)](PF6)(n) (orthorhombic, P2(1)2(1)2(1), a 10.879(7) Angstrom, b = 16.073(7) Angstrom, c = 9.19(1) Angstrom, Z = 4) and [Ag-n(MeSeCH(2)SeMe)(2n)](BF4)(n) (monoclinic, P2(1)/c, a 14.546(9) Angstrom, b = 14.65(1) Angstrom, c 30.203(9) Angstrom, Z = 4) reveal extended three-dimensional cationic frameworks in the solid state which contain large cylindrical or rectangular channels accommodating the PF6- or BE(4)(-) counterions. In contrast, a single-crystal X-ray structure of [Cu-n(MeSCH(2)SMe)(2n)](PFs)(n) . nMeNO(2) (orthorhombic, Pbcn, a 15.506(3) Angstrom, b = 8.934(2) Angstrom, c = 25.859(3) Angstrom, Z = 8) shows tetrahedral Cu(I) ions coordinated to bridging dithioethers forming an cationic ribbon-like arrangement of 8-membered rings. Adjacent rings are linked by the Cu atoms. Variable temperature NMR studies have been used to probe various exchange processes occurring in solution in these systems.
