Triethylsilyl triethylstannyl triethylstannane

Triethylsilyl Triethylstannyl Tellurium6 A two-necked, round-bottom flask fitted with a reflux condenser and a nitrogen inlet tube is flushed with nitrogen and charged with 7.14 g (35 mmol) of triethylstannane and 9.5 g (35 mmol) of ethyl triethylsilyl tellurium. The mixture is heated to 35" to initiate the reaction, the flask is cooled when the reaction becomes too vigorous. The reaction is allowed to preceed for 2 h. The resultant mixture is fractionated in a current of nitrogen under reduced pressure yield 14.2 g (91%) b.p. 109-11271 torr. 

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.
