Disiamylborane (bis(1,2-dimethylpropyl)borane) is an organoborane used in organic synthesis. It is used to add water to a terminal alkyne, forming an aldehyde via anti-Markovnikov addition. Disiamylborane is relatively selective for terminal alkynes. It also is used for the selective functionalization of terminal alkenes.
"Siamyl" is an abbreviation for sec-isoamyl. More modern conventions replace amyl with the pentyl group, and dispense with the sec and iso naming of pentyl isomers in favor of systematic naming as a substituted alkyl chain.
