, p. 863 - 867 (2010)
An ultrasound-assisted synthesis of functionalized symmetrical biaryls with electron-withdrawing or electron-donating substituents is described and illustrated by the palladium-catalyzed detelluration of 1,2-diarylditellanes. This procedure offers easy access to symmetrical biaryls in short reaction time and the products are achieved in good to excellent yields.

supporting information; experimental part, p. 4870 - 4873 (2010/01/06)
Alkyl aryl tellurides were efficiently transformed to the corresponding carbonyl compounds by photo-oxidation with sunlight without affecting various functional groups in the alkyl moiety. The tellurides can be used as a new carbonyl precursor, and the photolysis can be conducted without special equipment for light sources.
Method for preparing aromatic and olefinic organoselenium and organotellurium compounds

This invention constitutes a method of preparing molecular and supramolecular aromatic organic telluride, ditelluride, diselenide and selenide compounds from aromatic halogen compounds which are unactivated toward nucleophilic substitution. The method involves the reaction of an aromatic halide with an alkali metal telluride, ditelluride, selenide or diselenide reagent formed from chalcogen and alkali metal trialkylborohydride to yield the corresponding molecular or polymeric aromatic telluride, ditelluride, selenide or diselenide. Further, the alkali metal chalcogenide reagent prepared from alkali metal trialkylborohydrides may also be used to synthesize molecular and polymeric olefinic tellurides and selenides from olefinic halides unactivated toward nucleophilic substitution.
