Trimethylstannoxy

When an excess of tetramethylstannane was condensed on cis- or rran.s-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(hy droxy)stannane1. 

The reaction of cis- or trom-dihydroxy tellurium tetrafluoride with an excess of tetramethylstannane at 20° produced cis- or trans-bis[trimethylstannoxy] tellurium tetrafluoride in quantitative yields, as moisture-sensitive solids that can be sublimed under reduced pressure1. 

Cis- and ranj-hydroxy methoxy tellurium tetrafluoride reacted stereospecifically with chlorotrimethylsilane tetramethylstannane, and boron trichloride with elimination of hydrogen chloride or methane. The compounds obtained are trimethylsiloxy methoxy tellurium tetrafluoride trimethylstannoxy methoxy tellurium tetrafluoride, and boron tris[methoxo(oxo)tetrafluorotellurate (VI)]...
