Dibutyltin oxide Usage And Synthesis

Chemical Properties	Dibutyltin oxide (Bu2SnO, C8H18OSn, CAS registry No. 818-08-6) is a white fine powder. Its flash point is 81-83 °C. The solubility of HNQ is 4.0 mg/L in water at 20 °C. It is flammable when exposed to flame. It can react with oxidizing materials. To fight fire, use dry chemical, fog, CO2. When heated to decomposition, it emits acrid smoke and irritating fumes.
Uses	Dibutyltin oxide can be used as the catalyst in organic reaction.
Chemical Properties	white fine powder
Uses	Dibutyltin oxide is used in studies pertaining to discovering novel antitumor agents. Antifungal activity.
Uses	Di-n-butyltin oxide is used as a reagent and a catalyst. It is particularly useful in regioselective alkylation, acylation and sulfonation reactions for starting materials containing alcohol functional groups. It is used in studies pertaining to discovering novel antitumor agents, antifungal activity.
Flammability and Explosibility	Nonflammable
Safety Profile	Poison by ingestion and intraperitoneal routes. A skin and eye irritant. Flammable when exposed to flame; can react with oxidizing materials. To fight fire, use dry chemical, fog, CO2. When heated to decomposition it emits acrid smoke and irritating fumes. See also TIN COMPOUNDS.
Purification Methods	It is prepared by hydrolysis of di-n-butyltin dichloride with KOH. Hence wash it with a little aqueous M KOH, then H2O and dry at ~80o/10mm until the IR is free from OH bands. [Cummings Aust J Chem 18 98 1965, Beilstein 4 I 588.]
