The reaction of BH3 with alkynes always throws people off. The oxygen still ends up on the less substituted carbon, but now it looks like not one but two C-C double bonds have disappeared! This is usually the first introduction to the concept of “tautomerism“, and causes a fair amount of angst.
What does BH3 THF do in a reaction?
Borane–tetrahydrofuran (BH3–THF) is a charge-transfer complex that is a useful surrogate for diborane1 in organic synthesis. It can be used to reduce carboxylic acids to alcohols or nitriles to primary amines. It reacts with olefins to add the BH2 functional group.
What does Hydroboration oxidation do to an alkyne?
Hydroboration-oxidation converts a terminal alkyne into an aldehyde with the same number of carbon atoms.
