Acquired resistance
DIPHENYL DITELLURIDE is prepared by the action of aryllithium or arylmagnesium halides on tellurium powder followed by oxidation with air or with aqueous potassium ferricyanide. Electron-rich diaryl ditellurides (e.g. bis(2,4-dimethoxyphenyl) ditelluride) are prepared by reaction of the arene with tellurium tetrachloride to give the aryltellurium trichloride followed by reduction with Na2S2O5.
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(PPh
3)
4] in dichloromethane is reported to yield [Pd
