Trimethylsiloxy -stannoxy Tellurium Tetrafluorides

Refluxing cis- or trans-hydroxy methoxy tellurium tetrafluoride with an excess of chlorotrimethylsilane for 12 hours and distilling the reaction mixture, quantitatively produced cis- and trans-methoxy trimethylsiloxy tellurium tetrafluoride.  

Irgolic Organo-tellurium Compounds without a C,Te-Bond 

When an excess of tetramethylstannane was condensed on cis- or trans-hydroxy methoxy tellurium tetrafluoride and the mixture warmed to 20°, methane was liberated. Stirring the mixture for two hours and briefly heating it to 40°, produced, after evaporation of the excess tetramethylstannane, the colorless, low melting cis- or trans-methoxy trimethylstannoxy tellurium tetrafluoride in quantitative yields  

The trimethylstannoxy methoxy tellurium tetrafluorides hydrolyze in moist air with loss of trimethyl(hydroxy)stannane.  

Refluxing cis- or /rans-dihydroxy tellurium tetrafluoride with an excess of chlorotrimethyl-silane for 12 hours gave cis- or trans-bis[trimethylsiloxy]tellurium tetrafluoride in quantitative yields as distillable, eolorless liquids.
