Rational Design of an Organotellurium Chalcogen Bonding Catalyst for Azetidine Activation.

Angewandte Chemie
The application of chalcogen bonding catalysis has been largely confined to benchmark reactions due to the limited structural diversity and activating ability of the catalysts, especially those derived from tellurium.

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 ...

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.
