Boranes form interesting structures which cannot be described by the … It reacts readily with atmospheric 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… STABILITY BTHF is thermally unstable and must be kept cold. 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. It can be used to reduce carboxylic acids to alcohols or nitriles to primary amines. Experimental Physico-chemical Properties. Borane-tetrahydrofuran complex: EINECS: 237-881-8 CAS No. Articles of borane-diethylamine are included as well. These solutions are used for reductions and hydroboration, reactions that are useful in synthesis of organic compounds. Trihydridoboron, also known as borane or borine, is an unstable and highly reactive molecule with the chemical formula BH 3. 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. Predicted - ChemAxon. Borane, any of a homologous series of inorganic compounds of boron and hydrogen or their derivatives. Borane tetrahydrofuran complex solution 1.0 M in THF CAS Number 14044-65-6. 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. BTHF stabilized with <0.005 M NaBH 4 per mole of “BH 3”. This reaction is regioselective, Other borane derivatives can be used to give even higher regioselectivity. Borane–tetrahydrofuran is a dipolar bond charge-transfer complex composed of borane and tetrahydrofuran (THF). PubChem Substance ID 24850560. BTHF is susceptible to hydrolysis, readily reacting with water to form hydrogen and boric acid.

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 Molecular Weight 85.94 . 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. It reacts with olefins to add the BH 2 functional group. I've tried searching for a straightforward method to titrate borane-THF complex. Borane-tetrahydrofuran complex, 1M solution in THF, stabilized Revision Date 19-Jan-2018 9. Linear Formula BH 3 OC 4 H 8. Learn more about boranes in this article. 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). 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 BH3-THF can decompose violently, therefore BH3-THF is typically only available in 1 M concentration. I am a hydroboration rookie. Borane–tetrahydrofuran (BH 3 –THF) is a charge-transfer complex that is a useful surrogate for diborane 1 in organic synthesis. Borane-tetrahydrofuran complex, 1M solution in THF, stabilized Revision Date 19-Jan-2018 9. Chemsrc provides borane-diethylamine(CAS#:2670-68-0) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. The boron hydrides were first systematically synthesized and characterized during the period 1912 to roughly 1937 by the German chemist Alfred Stock. I could think of a simple reduction of simple aldehyde with of BH3-THF to alcohol. NACRES NA.22 However, the molecular species BH3 is a very strong Lewis acid.
