화학적 성질
WHITE CRYSTALLINE POWDER용도
9-BBN monomer acts as a selective hydroboration reagent in synthetic organic chemistry. It is employed in Suzuki reactions as well as in the preparation of terminal alcohols by the region selective addition of alkenes followed by oxidative cleavage using hydrogen peroxide. It is also used in copper-catalyzed cross-coupling reactions of organoboron compounds with primary alkyl halides and pseudohalides. It acts as a protecting group for alkenes. Further, it is used as a reactant for Hetero-Diels-Alder reaction for the synthesis of spirocyclic alkaloids. In addition to this, it is used in intramolecular insertion of alkenes into palladium-nitrogen bonds.일반 설명
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.Purification Methods
It is available as the solid dimer or in tetrahydrofuran solution. The solid is relatively stable and can be purified by distillation in a vacuum (as dimer) and by recrystallisation from tetrahydrofuran (solubility at room temperature is 9.5%, 0.78M), filter off the solid under N2, wash it with dry pentane and dry it in vacuo at ca 100o. The solid is a dimer (IR 1567cm-1), stable in air (for ca 2 months), and can be heated for 24hours at 200o in an inert atmosphere without loss of hydride activity. It is a dimer in tetrahydrofuran solution also (IR 1567cm-1). It is sensitive to H2O and air (O2) in solution. Its concentration in solution can be determined by reaction with MeOH and measuring the volume of H2 liberated, or it can be oxidised to cis-cyclooctane-1,5-diol (m 73.5-74.5o).

Dissolve it in Et2O and wash it with H2O in which it is insoluble. Evaporate the Et2O and distil the residual oil to gives better than 99.8% purity. Its vapour pressure is less than 0.1mm at room temperature. [Taylor et al. J Am Chem Soc 77 1506 1955, Beilstein 20 IV 2235.]9-Borabicyclo[3.3.1]nonane 준비 용품 및 원자재
