Crystal structure of borated N,N,N′,N′-tetramethyldiaminomethane
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the title compound, {[(dimethylamino)methyl]dimethylamine}trihydridoboron, C5H17BN2, the tetrahedral geometry of the N—C—N unit is slightly disorted. As a result of the bulky amine substituents, a wider N—C—N angle of 113.6 (1)° is observed.

Dehydrogenation of iron amido-borane and resaturation of the imino-borane complex
Chemical Science, 2021 Dehydrogenation of an amido-borane iron complex provides an imino-borane complex. Regeneration of the amido-borane precursor was achieved by protonation of the imino-borane followed by hydride transfer to the amino-borane intermediate.
