Tellurium tetramethoxide

Tellurium tetramethoxide, tetrabutoxide, and tetrapentoxide were similarly obtained. With polyalcohols, viscous brown materials were formed2. 

Tellurium tetramethoxide and tetraethoxide added two additional alkoxide ions when treated with sodium alkoxide in the appropriate alcohol2. 

When tellurium tetramethoxide or tellurium tetraisopropoxide in trifluorochloromethane at — 78° was reacted with elemental fluorine diluted with nitrogen, a mixture of tellurmm(VI) alkoxide fluorides that could not be separated by distillation were formed... 

When tellurium tetramethoxide and tetraethoxide in benzene were titrated with sodium alkoxide dissolved in the appropriate alcohol, sodium hydrogen hexaalkoxotellurates(IV) precipitated in crystalline form1. 

Selenium and tellurium alkoxides are also highly volatile and tend to be monomeric. For example, ethoxo-, -butoxo-, and isopropoxo-derivatives of selenium have been volatilized at 76°C/10.0, 110°C77.0, and 88°C/4.5mm pressures, respectively. Similarly tellurium tetramethoxide, ethoxide, -butoxide, and isopropoxide distilled at 115°C/9.0, 107°C/5.0, 150°C/0.8, and 76°C/0.5mm pressure, respectively.
