Triethylgermyl triethylsilyl

Pentane solutions of this compound decompose at 20° with loss of mercury to form triethylgermyl triethylsilyl tellurium4. 

Triethylgermyl triethylsilyltelluro mercury decomposed in hexane to triethylgermyl triethylsilyl tellurium5. 

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. 

Bis[triethylsilyl] tellurium reacted with triethylgermane with liberation of triethylsilane and formation of bis[triethylgermyl] tellurium6 1. Bis[triethylgermyl] tellurium and triethyl-stannane reacted similarly6,7. 

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. 

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

Triethylsilanetellurol, prepared from bis[triethylsilyl] tellurium and trifluoroacetic acid (s.p. 18), and bis[triethylgermyl] mercury yielded, depending on reaction conditions, mercury bis[triethylsilanetellurolate or triethylgermylmercury triethylsilanetellurolate. ... 

Bis[triethylsilyl] tellurium or bis[triethylgermyl] tellurium were heated with trisfpenta-fluorophenyl]bromostannane in toluene at 100° for two hours. Evaporation of the solvent, dissolution of the residue in petroleum ether, and chilling the solution to —10°, precipitated crystals of bis[tns(pentafluorophenyl)stannyl] tellurium (m.p. 118°) in 51% yield". ...
