Abstract:
Carboranyl substituted boranes are attractive Lewis acids for frustrated Lewis pair (FLP) chemistry due to their tremendous bulk and high Lewis acidity. In FLP chemistry, secondary boranes are uncommon Lewis acids due to the limited bulk. In this work, we interrogate bis(1-methyl-ortho-carboranyl)borane as a Lewis acid in FLP chemistry that reveals the secondary borane is sufficiently bulky to preclude adduct formation with a variety of Lewis bases and can be applied in bond activation reactions.

Hydroboration-Oxidation of Alkenes
Regioselectivity and Stereochemistry of Hydroboration
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn stereochemistry.

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
