Tellurium Tetraalkoxides

Tellurium tetraalkoxides are sensitive to moisture and fume in air. Upon storage at room 

---

Tellurium tetrachloride and sodium alkoxides combined in excess alcohol2, alcohol/ benzene3,4, or alcohol/tetrahydrofuran3 as the reaction medium to form tellurium tetraalkoxides. 

Tellurium tetraisopropoxide reacted with an excess of alkanols in refluxing benzene to produce tellurium tetraalkoxides and isopropanol. Ethanol or methanol reacted at 20° without benzene as solvent1. 

The tellurium tetraalkoxides were converted to tellurium tetrachloride on exposure to an excess of hydrogen chloride1. 

Tellurium tetraalkoxides and acetyl chloride reacted in benzene to produce tellurium alkoxide chlorides and alkyl acetate. The number of alkoxide groups remaining with the tellurium atom is determined by the molar ratio of the reagents3.
