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.
