Synthesis and properties of tris[tris (trimethylsilylmethyl) stannyl] thallium

1.	Tristris(trimethylsilylmethyl)stannyl]- and tristris(trimethylsilylmethyl)germyl] thallium, the first stable compounds containing Sn-Tl and Ge-Tl bonds, have been prepared by the reaction of the hydrides of tris (trimethylsilylmethyl)tin and tris (trimethylsilylmethyl)germanium with triethylthallium.
2.	The Sn-Tl bond is attacked in the reactions of the stannylthallium compound with lithium, mercury, oxygen, bromine, ethyl bromide, ethanol, and other reagents.
