Facile Synthetic Method of Na[BH3(NH2BH2)2H] Based on the Reactions of Sodium Amidoborane (NaNH2BH3) with NiBr2 or CoCl2

The reactions of sodium amidoborane (NaNH2BH3) with NiBr2 have been investigated, and the results showed that black precipitate 1 including the NiBNHx composites could be obtained. From the aqueous solution of the precipitate 1, the hydrolysis product Ni-B (2) was isolated and characterized. Both the in situ formed precipitate 1 and the hydrolysis product 2 can catalyze the formation of Na[BH3(NH2BH2)(2)H]. CoCl2 showed comparable performance with NiBr2. Based on these results, a facile method for the synthesis of Na[BH3(NH2BH2)(2)H] has been developed. This work provides insights into studying experimental methods for the synthesis of long B/N chain complexes and developing boron and nitrogen chemistry.

Automated summary

The research found that the reaction of sodium amidoborane with NiBr2 can produce black precipitate 1, leading to the isolation and characterization of hydrolysis product Ni-B (2), both of which can catalyze the formation of Na[BH3(NH2BH2)(2)H]. CoCl2 was observed to have similar performance to NiBr2, providing a new method for the synthesis of Na[BH3(NH2BH2)(2)H].
