How is Hexabutyldistannane (CAS: 813-19-4) typically synthesized?

Hexabutyldistannane is typically synthesized by the reaction of dibutyltin dichloride with n-butanol in the presence of a catalyst such as tin(II) chloride. The reaction is usually carried out at room temperature and yields a high purity product with excellent selectivity. This method ensures a high yield of the desired hexabutyldistannane.
