Pinacolborane
Pinacolborane is the borane with the formula 4C2O2BH. It features a five-membered C2O2B ring. Owing to the presence of the alkoxide substituents, it is a monomer. It is a colorless liquid prepared by treating borane adducts with pinacol. It features a reactive B-H functional group.In the presence of catalysts, pinacolborane hydroborates alkenes and, less rapidly, alkynes.
Pinacolborane also effects catalyst-free hydroboration of aldehydes, ketones, and carboxylic acids.
Pinacolborane is used in borylation, a form of C-H activation.Related compounds
