Organotellurium Compounds in Organic Synthesis

Russian Chemical Reviews, 1987
The review gives a systematic account of the survey of data on the application of organic compounds of tellurium in the synthesis of hydrocarbons, halogeno-derivatives, and carbonyl compounds. The bibliography includes 94 references.

Incorporation of organotellurium(IV) in polyoxometalates

Journal of Organometallic Chemistry, 2015
Abstract We report on the synthesis and solid-state characterization of two sandwich-type heteropoloytungstates containing three cyclobutyltellurium(IV) units, [(C4H8TeIV)3(XIIIW9O33)2]12− (X = As, 1; Sb, 2). Polyanions 1 and 2 were prepared by reaction of cyclobutyltellurium(IV)diiodide (C4H8TeI2) and the trilacunary, lone-pair-containing POM ...

Role of Organotellurium Species in Tellurium Neuropathy

Neurochemical Research, 1998
Exposure of weanling rats to a diet containing 1% elemental tellurium causes segmental demyelination of peripheral nerve, and an inhibition of squalene epoxidase. This inhibition is thought to be the mechanism of action leading to demyelination. Tellurite appears to be the active inhibitory species in a cell-free system but the active species in vivo ...

Thermodynamics of organoselenium and organotellurium compounds

Russian Chemical Reviews, 1995
Experimental values of the enthalpies of formation (ΔHf°) and of the specific heat (Cp°) of the organic compounds of selenium and tellurium, are discussed, including their complexes with dialkylzinc and dialkylcadmium. Different forms of the methods of combustion enthalpy and of reaction calorimetry, used to determine ΔHf° values, are examined.

Organotellurium derivatives of dicarboxylic acids

Journal of Organometallic Chemistry, 1976
Abstract The freshly prepared sodium salts of ortho-phthalic acid and tetrabromo ortho-phthalic acid react with diaryltellurium dichlorides in chloroform to afford new dimeric organotellurium carboxylates, R2Te(C8X4O4)2 (X = H, Br). The new compounds contain fourteen membered rings and the detailed structure is discussed particularly in the light of ...

Generation of an Organotellurium(II) Cation

European Journal of Inorganic Chemistry, 2012
AbstractWe expected that the chemical trapping products of low‐coordinated tellurenyl cation species can also be kinetically stabilized by the Tbt or Bbt group. Recently, we have reported the halogenation reactions of Bbt‐substituted ditelluride, BbtTeTeBbt, leading to the formation of the TeII–TeIV mixed‐valent tellurenyl fluoride, BbtTeTe(F)2Bbt, and

Organotellurium-catalyzed oxidative deoximation reactions using visible-light as the precise driving energy

, 2020
Irradiated by visible light, the recyclable (PhTe)2-catalyzed oxidative deoximation reaction could occur under mild conditions. In comparison with the thermo reaction, the method employed reduced catalyst loading (1 mol% vs.
