Synthesis and structural aspects of 1-naphthyltellurium(IV) trichloride (1), bis(mesityl)tellurium(IV) dichloride (2) and bis(chlorobis(2-thiophenyl) tellurium)oxide (3)

Chlorination of bis(1-naphthyl)ditelluride (NplTeTeNpl; Npl = 1-C 10H7) with 3 equiv. of sulfuryl chloride (SO 2Cl2) resulted in bright yellow crystals of 1-naphthyltellurium(IV) trichloride (1-NplTeCl3/su

Platinum-Mediated Activation of Coordinated Organonitriles by Telluroethers in Tetrahydrofuran: Isolation, Structural Characterization, and Density Functional Theory Analysis of Intermediate Complexes

The reactions of [PtCl2(NCR)2] with telluroethers (ArAr′Te) in organic solvents have been investigated. The reactions in dichloromethane yield [PtCl2(TeArAr′)2], while those in tetrahydrofuran (THF) give different products depending on the steric demands of the aryl groups on tellurium, the molarity of the reactants, and the reaction conditions. The reactions between [PtCl2(PhCN)2] and TeArAr′ in 1:1 molar ratio at room temperature in THF yield several products, like [PtCl2(TeArAr′)2] (Ar/Ar′ = Ph/Ph, o-tol/Mes, Mes/Mes), [PtCl2(PhCN){NC(O)Ph[TeMes(o-tol)]}], and [PtCl2{NC(O)Ph(TeMes2)}2]. The reaction with TeMes2 in refluxing THF gave [PtCl2{NC(Ph)C4H7O}{NC(O)Ph(TeMes2)}] and [PtCl(TeMes2){Te(Mes)CH2C6H2Me2}], depending on the duration of heating. Reaction of [PtCl2(PhCN)2] with TeArMes afforded [PtCl2(TeArMes)2] (Ar = Ph, o-tol, and Mes), the formation of which decreased with increasing steric demand of the Ar group, together with [PtCl2{NC(O)Ph(TeArMes)}2]. The telluroether in the latter binds to nitrogen, and tellurium exists in the formal oxidation state of +4 (from XPS). The tellurium in these complexes exhibits secondary interactions with platinum (J(195Pt-125Te) = 309-347 Hz) and with the carbonyl oxygen. These complexes slowly dissociate in solution to give [PtCl2(TeMesAr){NC(O)Ph(TeMesAr)}], finally leading to the formation of [PtCl2(TeMesAr)2]. Molecular structures of trans-[PtCl2(PhCN){NC(O)Ph[TeMes(o-tol)]}], trans-[PtCl2{NC(O)Ph(TeMes2)}2], trans-[PtCl2{NC(Ph)C4H7O}{NC(O)Ph(TeMes2)}], trans-[PtCl2{NC(O)Ph[TeMes(o-tol)]}2], trans-[PtCl2(TeMes2){NC(O)Ph(TeMes2)}], trans-[PtCl2{NC(O)Me(TeMes2)}2], and [PtCl(Te-o-tol){NC(O)Ph}2] have been unambiguously established by single-crystal X-ray diffraction analyses. Density functional theory calculations for some of the complexes were performed, and geometrical parameters are in good agreement with the values obtained from X-ray analyses.

Role of anagostic interactions in cycloplatination of telluroethers: Synthesis and structural characterization

Abstract Reactions of K2PtCl4 with TeRRE′ gave complexes of composition [PtCl2(TeRRE′)2] (R/RE′ = Ph2(1a), o-tol2 (1b), Mes2(1c), Ph/Mes (1d), o-tol/Mes (1e)). The complex [PtCl2(TeMes2)2] in refluxing THF afforded a mononuclear cyclometalated complex [PtCl{(CH2C6H2Me2-4,6)TeMes}(TeMes2)] (2). It tends to remain in equilibrium with a binuclear derivative [Pt(μ-Cl){(CH2C6H2Me2-4,6)TeMes}]2 (3) in CDCl3 solution. The complexes 1d and 1e did not undergo cyclometalation reaction under similar reaction conditions. The 2 on treatment with PPh3 gave [PtCl{(CH2C6H2Me2-4,6)TeMes}(PPh3)] (4). All the complexes have been characterized by elemental analysis and NMR (1H, 31P, 125Te, 195Pt) spectroscopy. Anagostic interactions have been recognised for facilitation of cyclometalation reactions. The molecular structures of trans-[PtCl2(TeMes2)2] (1c), trans-[PtCl2(PhTeMes)2] (1d), trans-[PtCl2(o-tolTeMes)2] (1e), [PtCl{(CH2C6H2Me2-4,6)TeMes}(TeMes2)] (2) and [PtCl{(CH2C6H2Me2-4,6)TeMes}(PPh3)] (4) have been established unambiguously by single crystal X-ray diffraction analyses.

Cyclopalladation of telluro ether ligands: Synthesis, reactivity and structural characterization

Treatment of [PdCl2(PhCN)2] with diaryl telluride in 1:2 molar ratio gave mononuclear palladium complexes, trans-[PdCl2(TeR2)2] (1) (R = Mes (1a) (Mes = 2,4,6-trimethylphenyl), Ph (1b), o-tol (1c) (o-tol = ortho-tolyl)). Reaction of [PdCl2(TeMes2)2] with one equivalent of [PdCl2(PhCN)2] or Na2PdCl4 with TeRR′ afforded chloro-bridged binuclear complexes, [Pd2(μ-Cl)2Cl2(TeRR′)2] (2) (R/R′ = Mes/Mes (2a); Mes/Ph (2b); Ph/Ph (2c)). A toluene-methanol solution of trans-[PdCl2(TeMes2)2] on refluxing for 30 minutes yielded a binuclear cyclopalladated complex, [Pd2(μ-Cl)2{CH2C6H2(4,6-Me2)TeMes)}2] (3). When the refluxing was prolonged, a mononuclear complex cis-[PdCl2{MesTeCH2C6H2(4,6-Me2)TeMes}] (4) was isolated. Treatment of palladium acetate with TeMes2 afforded an acetato-bridged analogue of 3, [Pd2(μ-OAc)2{CH2C6H2(4,6-Me2)TeMes}2] (5a) together with a very minor component, a tetranuclear complex, [Pd(μ-OAc)(μ-TeMes)]4 (6). This reaction with unsymmetrical tellurides, MesTeR, also gave cyclopalladated complexes [Pd2(μ-OAc)2{CH2C6H2(4,6-Me2)TeR}2] (R = o-tol (5b) and Ph (5c)) in which 2-methyl of the mesityl group of the telluride was exclusively metallated. The complex trans-[PdCl2(TeMes2)2] on refluxing in xylene gave palladium telluride, Pd7Te3. These complexes were characterized by elemental analyses, IR and NMR (1H, 13C and 125Te) spectroscopy. The molecular structures of trans-[PdCl2(TeMes2)2] (1a), [Pd2(μ-Cl)2Cl2(TeMes2)2]·2acetone (2a·2acetone), cis-[PdCl2{MesTeCH2C6H2(4,6-Me2)TeMes}] (4), [Pd2(μ-OAc)2{CH2C6H2(4,6-Me2)TeMes)}2]·toluene (5a·toluene), [Pd2(μ-OAc)2{CH2C6H2(4,6-Me2)Tetol-o}2] (5b) and [Pd(μ-OAc)(μ-TeMes)]4 (6) were established by single crystal X-ray diffraction analyses. The mononuclear complex 1a was isolated in two polymorphic forms each with the trans configuration. This journal is

Aerobic photooxidation of phosphite esters using diorganotelluride catalysts

Diorganotellurides containing bulky aromatic substituents are found to catalyze the photooxidation of phosphite esters using aerobic oxygen as a terminal oxidant. A Hammett plot with substituted triaryl phosphites yielding p = 2.88 agrees with a nucleophilic oxygen transfer from telluroxide to phosphite.2009 American Chemical Society.

Diaryl tellurium dihalides: From Te-tetracoordinated compounds to Te-tricoordinated molecular complexes

X-ray structural studies demonstrate that diaryl tellurium diiodides can be constrained by steric factors (ortho-alkyl substituents) to adopt a trigonal pyramidal structure in preference to the expected bisphenoidal structure. DFT calculations are shown to reproduce successfully structural details of the title compounds; they allow one to predict which coordination number should be energetically favored. All compounds are chiral, but the barrier to stereomutation by intra- and intermolecular pathways (60-85 kJmol-1) is rather low. Copyright Taylor & Francis Inc.
