Sign in to saveAlso known as bis(1,2-dimethylpropyl)borane, Sia2BH
Disiamylborane (bis(1,2-dimethylpropyl)borane) is an organoborane with the formula (abbreviation: Sia2BH). It is a colorless waxy solid that is used in organic synthesis for hydroboration–oxidation reactions. Like most dialkyl boron hydrides, it has a dimeric structure with bridging hydrides.

Disiamylborane (bis(1,2-dimethylpropyl)borane) is an organoborane with the formula (abbreviation: Sia2BH). It is a colorless waxy solid that is used in organic synthesis for hydroboration–oxidation reactions. Like most dialkyl boron hydrides, it has a dimeric structure with bridging hydrides.
==Reactions== Disiamylborane is prepared by hydroboration of trimethylethylene with diborane. The reaction stops at the secondary borane due to steric hindrance.
