Hexamethyldistannane Structural

What is Hexamethyldistannane?

Chemical properties

Clear colorless liquid

The Uses of Hexamethyldistannane

Agricultural chemical.

The Uses of Hexamethyldistannane

It is used to prepare aryl tin compounds for microwave-assisted Stille cross-coupling with halo pyridines or copper-mediated O-arylation of phenols.

Hazard

A poison by ingestion.

Purification Methods

Wash it with H2O and extract with *C6H6, dry by filtering through powdered Na2SO4, remove *C6H6 on a rotary evaporator and fractionally distil the oily residue under vacuum (b 85-88o/45mm). It boils at ca 182o at atmospheric pressure, but it cannot be distilled in air because the hot vapours flash in the condenser.
