However, the molecular species BH3 is a very strong Lewis acid. Borane–tetrahydrofuran (BH 3 –THF) is a charge-transfer complex that is a useful surrogate for diborane 1 in organic synthesis. Consequently it is highly reactive and can only be observed directly as a continuously produced, transitory, product in a flow system or from the reaction o… I've tried searching for a straightforward method to titrate borane-THF complex. Borane tetrahydrofuran complex solution, 1.0 M in THF, contains 0.005 M N-Isopropyl-N-methyl-tert-butylamine as stabilizer, Sorry we cannot compare more than 4 products at a time.

Molecular Weight 85.94 . Borane-tetrahydrofuran complex, 1M solution in THF, stabilized Revision Date 19-Jan-2018 9. This reaction is regioselective, Other borane derivatives can be used to give even higher regioselectivity. I am a hydroboration rookie. Predicted - ChemAxon. Borane, any of a homologous series of inorganic compounds of boron and hydrogen or their derivatives. Flash point (closed cup): -5.7 oF (-22 oC) Boiling point: 66 oC for THF, see Stability sec. These solutions are used for reductions and hydroboration, reactions that are useful in synthesis of organic compounds. Boranes form interesting structures which cannot be described by the … Trihydridoboron, also known as borane or borine, is an unstable and highly reactive molecule with the chemical formula BH 3. MDL number MFCD00012429. Borane can be made from magnesium boride (MgB 2) with the action of acid or can be prepared by the breaking apart of complex molecules into simpler products on heating in the presence of hydrogen. Learn more about boranes in this article. Experimental Physico-chemical Properties. BTHF is susceptible to hydrolysis, readily reacting with water to form hydrogen and boric acid. The preparation of borane carbonyl, BH3(CO), played an important role in exploring the chemistry of boranes, as it indicated the likely existence of the borane molecule. Borane–tetrahydrofuran is a dipolar bond charge-transfer complex composed of borane and tetrahydrofuran (THF). Borane adducts are widely used in organic synthesis for hydroboration, where BH 3 adds across the C=C bond in alkenes to give trialkylboranes: (THF)BH 3 + 3 CH 2 =CHR → B(CH 2 CH 2 R) 3 + THF. I could think of a simple reduction of simple aldehyde with of BH3-THF to alcohol. Borane tetrahydrofuran complex solution, 1.0 M in THF, contains 0.005 M N-Isopropyl-N-methyl-tert-butylamine as stabilizer Borane-tetrahydrofuran complex, BTHF-1M in THF contains 0.005M sodium borohydride as stabilizer It can be used to reduce carboxylic acids to alcohols or nitriles to primary amines. Articles of borane-diethylamine are included as well. It reacts with olefins to add the BH 2 functional group. -108.5 °C Oakwood [044988] Experimental Boiling Point: 65.5-66.5 °C SynQuest 72692, 78515, 6H60-1-13, 6H60-1 … STABILITY BTHF is thermally unstable and must be kept cold. The boron hydrides were first systematically synthesized and characterized during the period 1912 to roughly 1937 by the German chemist Alfred Stock. 14044-65-6: Density: 0.898 g/mL at 25 °C Solubility: Soluble in THF and react with water Melting Point: Formula: C 4 H 11 BO Boiling Point: 68.3 °C at 760 mmHg Molecular Weight: 85.94 Physical and chemical properties Physical State Liquid Appearance Colorless Odor Stench Odor Threshold No information available pH No information available Melting Point/Range-108 °C / -162.4 °F Boiling Point/Range approx 66 °C / 150.8 °F Physical and chemical properties Physical State Liquid Appearance Colorless Odor Stench Odor Threshold No information available pH No information available Melting Point/Range-108 °C / -162.4 °F Boiling Point/Range approx 66 °C / 150.8 °F Beilstein/REAXYS Number 3668402 . Chemsrc provides borane-diethylamine(CAS#:2670-68-0) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Experimental Melting Point: -108 °C SynQuest 72692, 78515, 6H60-1-13, 6H60-1-16. It reacts readily with atmospheric BH3-THF can decompose violently, therefore BH3-THF is typically only available in 1 M concentration. NACRES NA.22 Borane-tetrahydrofuran complex: EINECS: 237-881-8 CAS No. Borane tetrahydrofuran complex solution 1.0 M in THF CAS Number 14044-65-6. It is recommended that BH3-THF solutions be stored at 0-5 C, and that reactions are performed at under 35 C. Borane-dimethylsulfide ( BH3-SMe2 ) is more stable than BH3-THF and is available in much higher concentrations (10 M). PubChem Substance ID 24850560. Borane tetrahydrofuran complex solution, 1.0 M in THF, contains 0.005 M N-Isopropyl-N-methyl-tert-butylamine as stabilizer, Sorry we cannot compare more than 4 products at a time.
