Diethylalumino triethylsilyl

When triethylsilanetellurol reacted with triethyl aluminum in hexane at 20°, ethane was liberated, and the very air- and moisture-sensitive diethylalumino triethylsilyl tellurium was isolated in the form of colorless crystals2,3. 

Diethylalumino Triethylsilyl Tellurium3 A solution of 1.06 g (9.3 mmol) of triethyl aluminum in 5 ml of hexane is placed in an ampoule purged with argon. The ampoule is cooled to 0° and 2.26 g (9.3 mmol) of triethylsilanetellurol are added gradually. The mixture is then filtered through a glass frit, the filtrate is cooled to — 78°, and the precipitated crystals are recrystallized three times from hexane at — 78° under argon yield 1.06g (35%) m.p. 34° (dec.).
