Synthesis and application of organotellurium compounds

Physical Sciences Reviews, 2022
Abstract Organotellurium compounds define the compounds containing carbon (organic group) and tellurium bond (C–Te). The first organic compound containing tellurium was prepared by Wohler in 1840 after the discovery of the metal by the Austrian chemist F. J. Muller von Reichenstein in the year 1782.

Stabilisation of PVC with organotellurium compounds

Polymer Degradation and Stability, 1988
Abstract Organotellurium compounds are shown to behave similarly to organotin compounds as thermal and UV stabilisers for PVC. The most effective of these, the dialkyltellurium maleates, were, however, less effective than the corresponding tin compounds but the study points the way to further progress in the design of organometallic compounds as PVC ...

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 ...

Addition of organotellurium trihalides to acetylenes

Organometallics, 1991
(p-Methoxyphenyl)tellurium trichloride reacts with terminal acetylenes to give 1-chloro-1-organyl-2-[dichloro(p-methoxyphenyl)telluro] ethenes of Z configuration in good yields. The Z stereochemistry of the addition products suggests that the reaction occurs through a four-centered cyclic transition state.
