Description
As a source of tributylstannyl radicals,Hexabutylditin is used in palladium-catalyzed tin-carbon bond formation, deoxygenation and desulfurization reactions.
Chemical Properties
Clear colorless to slightly yellow liquid
Uses
Hexabutylditin (CAS# 813-19-4) is a building block used to synthesize stannylation of aryl halides, or to prepare functionalized arylstannates via Pd-catalyzed cross-coupling reactions.
Synthesis
Hexabutylditin can also be obtained from Tri-n-butylchlorostannane and either lithium, sodium, or magnesium, from tributyltin chloride and Tri-n-butylstannyllithium (the latter from tributyltin hydride and Lithium Diisopropylamide), or by catalytic elimination of hydrogen from tributyltin hydride.
Purification Methods
Purify it by distilling it in a vacuum and store it in the dark. [Shirai et al. Yakugaku Zasshi 90 59 1970, Chem Abstr 72 90593 1970, Beilstein 4 I 590.]
