General description

Diphenyl ditelluride (PhTe)2 is a versatile reagent used in the organic synthesis. Neurotoxicity by (PhTe)2 depends on the modulation of signaling pathways initiated at the plasma membrane. Comparative toxicological effects of diphenyl diselenide and (PhTe)2 in mice after in vivo administration has been reported. Teratogenic effects of (PhTe)2 on chicken embryo development has been investigated. The oxidative addition of (PhTe)2 to [Pd(PPh3)4] in dichloromethane is reported to yield [Pd6Cl2Te4(TePh)2(PPh3)6]·1/2CH2Cl2.

Application

Diphenyl ditelluride may be used in the assay of organolithium and Grignard reagents.

Organoselenium compounds have been pointed out as therapeutic agents. In contrast, the potential therapeutic aspects of tellurides have not yet been demonstrated. The present study evaluated the comparative toxicological effects of diphenyl diselenide (PhSe)2 and diphenyl ditelluride (PhTe)2 in mice
