Description générale

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.[1][2]

Application

Differentiation of symmetrical diols by reduction of the corresponding cyclic acetals with 9-BBN.[3]
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.[4][5][6]

Conditionnement

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

Several useful aryl/alkyl building blocks for dendrimer and hyperbranched polymer synthesis were prepared by Suzuki-Miyaura cross-coupling reactions and iododesilylation reactions. The iododesilylations were carried out with iodine monochloride (ICl) in methylene chloride and diethyl ether (10:1). This solvent combination lowered

Questions

1–2 sur 2 questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 réponse

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 réponse

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
