Applications
TeCl4 has proven of occasional interest in organic synthesis. It adds to alkenes to give Cl-C-C-TeCl3 derivatives, wherein the Te can be subsequently removed with sodium sulfide. Electron-rich arenes react to give aryl Te compounds. Thus anisole give TeCl2(C6H4OMe)2, which can be reduced to the diaryl telluride.
