Popis

General description

9-Borabicyclo[3.3.1]nonane is an organic compound, which is generally used as a hydroborating agent. It is thermally stable, less sensitive to oxygen and water when compared to other dialkyl boranes. It is commonly used to prepare aldehydes from alkynes.

Application

Differentiation of symmetrical diols by reduction of the corresponding cyclic acetals with 9-BBN.

Protecting group for alkenes†

Reactant for:

• Linear SPPS synthesis of ubiquitin derivatives
• Copper-catalyzed cross-coupling reactions of organoboron compounds with primary alkyl halides and pseudohalides
• Intramolecular insertion of alkenes into palladium-nitrogen bonds
• Preparation of (phosphonoacetyl)ornithine to study effect on arginine biosynthetic genes in yeast
• Hetero-Diels-Alder reaction for synthesis of spirocyclic alkaloids

Selective hydroboration reduction reagent.

Packaging

The 25 mL Sure/Seal^™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
