The TeF5 group is significantly underexplored as a highly fluorinated substituent on an organic framework, despite it being a larger congener of the acclaimed SF5 group. In fact, only one aryl-TeF5 compound (phenyl-TeFsub
Iron-catalyzed formation of C-Se and C-Te bonds through cross coupling of aryl halides with Se(0) and Te(0)/nano-Fe3O4@GO

The formation of C-Se and C-Te bonds is of synthetic and biological importance. Graphene oxide based nano-Fe3O4 (nano-Fe 3O4@GO) is used as a reusable catalyst for the efficient synthesis of diselenides and ditellurides, through cross coupling of Se(0) or Te(0) with aryl iodides. The magnetic heterogeneous catalyst could be easily recovered and reused many times without significant loss of catalytic activity. In addition the superiority of nano-Fe3O4@GO over pristine nano-Fe3O4 is established. Georg Thieme Verlag Stuttgart. New York.
Ultrasound-assisted synthesis of symmetrical biaryls by palladium-catalyzed detelluration of 1,2-diarylditellanes

experimental part, p. 863 - 867 (2010/03/24)
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.
Direct Synthesis of Some Diaryl Ditellurides from Aryl Halides
Liu, Jianfei,Qiu, Mei,Zhou, Xunjun
, p. 2759 - 2767 (2007/10/02)
The reaction of aryl halides with sodium hydrogen telluride in dimethylformamide is studied.Some diaryl ditellurides are synthesized under mild conditions by the reaction.
Improved preparation of diaryl ditellurides
Engman, Lars,Persson, Joachim
, p. 71 - 74 (2007/10/02)
Diaryl ditellurides have been synthesized from aryl bromides via lithiation, tellurium insertion, and ferricyanide oxidation of the resulting lithium arenetellurolates.
