Bi(I)-Catalyzed Transfer-Hydrogenation with Ammonia-Borane. [PDF]
J Am Chem Soc, 2019 A catalytic transfer-hydrogenation utilizing a well-defined Bi(I) complex as catalyst and ammonia-borane as transfer agent has been developed. This transformation represents a unique example of low-valent pnictogen catalysis cycling between oxidation ...

Acta Crystallographica Section E Structure Reports Online, 2011 The asymmetric unit of the title compound, C(18)H(18)BN or (C(6)H(5))(3)B·NH(3), comprises two crystallographically independent but virtually identical mol-ecules. Mol-ecules of one type are linked with each other by N-H⋯π inter-actions, generating an infinite column aligned along the b-axis direction.

On the origin of internal rotation in ammonia borane [PDF]
Journal of Molecular Modeling, 2014 The internal rotation in ammonia borane (AB) was studied on the basis of natural orbitals for chemical valence (NOCV) and eigenvectors for Pauli repulsion (NOPR). We found that the total hyperconjugation stabilization (ca. 5 kcal mol(-1)), based on the charge transfer from the occupied σ (B-H) orbitals into the empty σ*(N-H), slightly favors the ...

Nanostructured Carbon-Doped BN for CO2 Capture Applications
Nanomaterials, 2023 Carbon-doped boron nitride (denoted by BN/C) was prepared through the pyrolysis at 1100 °C of a nanostructured mixture of an alkyl amine borane adduct and ammonia borane. The alkyl amine borane adduct acts as a soft template to obtain nanospheres.

Titanium-Mediated Reduction of Carboxamides to Amines with Borane–Ammonia
Molecules, 2023 In this study, the successful titanium tetrachloride-catalyzed reduction of aldehydes, ketones, carboxylic acids, and nitriles with borane–ammonia was extended to the reduction (deoxygenation) of a variety of aromatic and aliphatic pri-, sec- and tert ...

Anharmonic vibrational frequencies of ammonia borane (BH3NH3) [PDF]
The Journal of Chemical Physics, 2021 The fundamental vibrational frequency of the B–N stretch in BH3NH3 has eluded gas-phase experimental observation for decades. This work offers a theoretical anharmonic prediction of this mode to be 644 cm−1, using a Cartesian quartic force field at the CCSD(T)-F12/cc-pVTZ-F12 level of theory.
