Ethyl triethylgermyl

Ethyl triethylsilyl and ethyl triethylgermyl tellurium reacted with triethylstannane at 20° to produce triethylsilyl(-germyl) triethylstannyl tellurium5 6. 

When diethyl tellurium was heated with triethylsilane at 200° for seven hours, or with triethylgermane at 140° for seven hours, the Te — C bond was cleaved, ethane liberated, and mixtures of ethyl triethylsilyl tellurium/bis[triethylsilyl] tellurium or ethyl triethylgermyl telluriumlbis[triethylgermyl] tellurium were formed6. However, triethylstannane and diethyl tellurium yieled only bis[triethylstannyl] tellurium even at 20° 5 6. 

Ethyl Triethylgermyl Tellurium [from Triethylgermyl Lithium]1 1.56 g (3.0 mmol) of bisjtriethylgermyl] mercury are reacted with 0.5 g (72 mmol) of lithium in 30 ml of hexane under an inert atmosphere. 1.55 g (5.0 mmol) of diethyl ditellurium are added to the resultant solution of triethylgermyl lithium. After 5 min, the mixture is cooled to — 196° and 1.87 g (7.8 mmol) of bromotriethylgermane are added. The mixture is allowed to warm to 20°, shaken for 10 min, filtered, and the solvent is evaporated yield 2.8 g (89%). 

Ethyl Triethylgermyl Tellurium [from Bis(triethylgermyl) Mercury]2 Under an inert atmosphere, 3.27 g (6.3 mmol) of his[triethylgermyl] mercury are mixed with 1.97 g (6.3 mmol) of diethyl ditellurium. The mixture is kept at 20" for 24 h, filtered, and the filtrate is distilled under vacuum yield 2.91 g (73%) b.p. 61 °/l torr. 

Ethyl Triethylgermyl Tellurium3 Under an inert atmosphere, a mixture of 7.86 g (42 mmol) of diethyl tellurium and 8.0 g (50 mmol) of triethylgermane is heated at 140" for 7 h whereby 1100 ml of ethane are evolved. The mixture is then fractionated under reduced pressure of nitrogen yield 5.2 g (39%) b. p. 61 /1 torr. 

Ethyl triethylgermyl tellurium and ethyl triethylsilyl tellurium reacted with trieth-ylstannane at 20c forming diethyl tellurium and triethylstannyl triethylsilyl (or -germylj tellurium4... 

Diethyl ditellurium and bis[triethylgermyl] mercury yielded ethyl triethylgermyl tellurium3. Triorgano tin hydrides cleave the Te — Te bond in diaryl and dialkyl ditellurium compounds forming the organo triorganostannyl tellurium as one of the products (p. 191). 

Lithium ethanetellurolate condensed with silyl chlorides and with triethylgermyl chloride to form ethyl silyl (germyl) tellurium compounds6. 

Ethyl triethyhilyl tellurium (11% b.p. 53°/l torr) was similarly prepared by heating the reactants at 200°. Bis[triethylsilyl] tellurium and bis[triethylgermyl] tellurium are also formed in these reactions3,4.
