H/D scrambling in a chromium-catalyzed dehydrocoupling reaction of a borane-dimethylamine adduct

H/D scrambling took place in a chromium-catalyzed dehydrocoupling reaction of a deuterium-labeled borane-dimethylamine adduct. In the hydrogen elimination of BH3·NDMe2 (1a-dN), H2, HD and D2 were generated in 65:30:5 ratio, and 62% of deuterium atoms were incorporated into the major product, the dimethylaminoborane dimer. Proton and deuteron nuclei were thus concentrated into the evolved dihydrogen and aminoborane dimer, respectively. The mechanism of H/D scrambling is understood based on the reaction pathway of the dehydrocoupling of 1a, which was previously proposed based on DFT calculations. The H/D distribution in the products is explained by the energy difference according to the deuterated position in an intermediate of the dehydrocoupling reaction.

Paragraph 0035; 0036, (2017/12/05)
The invention belongs to the technical field of material preparation, in particular relates to a method for the production of amine borane complex. This invention adopts the borane amine of the direct reaction of an inert gas stream, by regulating the ratio of the two, the need for further post-processing, to make the final product amine complex and offer. In the reaction process such impurity is introduced into the salt-free, does not use an organic solvent; the use of borohydride such as the reagent to produce the borane, for now the current system, can avoid direct operation of toxic gas borane. The method of the invention is simple in operation, the product has high purity, low cost, and can be continuous large-scale production. At the same time, the method and other way to produce the amine borane complex equipment compatible, production equipment by simple method can be used to adjust the production.
