Sulfurized metal borohydrides

Dalton Transactions, 2016
The reactions between metal borohydrides and elemental sulfur are investigatedin situduring thermal treatment and are found to be highly exothermic (up to 700 J g−1).

Tetrabutylammonium borohydride and its complex with aluminum borohydride

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1971
1. Tetrabutylammonium borohydride was obtained by the exchange reaction of tetrabutylammonium bromide with excess sodium borohydride in ether isopropyl alcohol or benzene medium. 2. Tetrabutylammonium borohydride aluminate, [(C4H9)4N] [Al(BH4)4], was synthesized by the reaction of the tetrabutylammonium and aluminum borohydrides.

Borohydride as Magnetic Superexchange Pathway in Late Lanthanide Borohydrides

European Journal of Inorganic Chemistry, 2019
The magnetic characteristics of a series of borohydride‐based systems, including binary α‐/β‐Ln(BH4)3 phases (Ln = Gd, Tb, Dy, Ho, Er, and Tm) with direct Ln–HBH–Ln bridges and selected mixed‐metal systems, LiYb(BH4)4, NaYb(BH4)4, KHo(BH4)4, RbTm(BH4)4, with isolated Ln3+ ions embedded in [Ln(BH4)4]– anions are described for the first time using SQUID ...

Calcium Borohydride

Synthetic Communications, 1995
Calcium borohydride reduces both aliphatic and aromatic esters to alcohols completely in the presence of alkene catalysts. The intermediate borates formed during the reduction of aromatic esters are converted to aldehydes with aqueous NaOC1 in good yields.

Hindered rotation of the borohydride ion in potassium and sodium borohydride

The Journal of Chemical Physics, 1974
The hindered rotational energy levels of the borohydride ion in the high temperature phases of NaBH4 and KBH4 have been computed. The Hamiltonian which describes the motion of the borohydride ion in NaBH4 is invariant under the direct product group Ō × O, while the Hamiltonian for the borohydride ion in KBH4 is invariant under the direct product group ...

Reductions with sulfurated borohydrides. I. Preparation of sulfurated borohydrides

Canadian Journal of Chemistry, 1968
Sodium borohydride reacts with sulfur at room temperature in the presence of appropriate organic solvents to give a sulfurated borohydride: NaBH2S3. The formulation of this hydride has been established by infrared, nuclear magnetic resonance, and elementary analysis. Thermal decomposition and hydrolysis are reported.

Reductions with sulfurated borohydrides. III. Borohydrides incorporating selenium and tellurium

Canadian Journal of Chemistry, 1969
The reactions of selenium and tellurium with lithium, sodium, potassium, and tetramethylammonium borohydrides have been examined, using the hydrogen evolution as a measurement of the replacement of hydrogen by the chalcogen on the borohydride anion.

Preparation of Quaternary Ammonium Borohydrides from Sodium and Lithium Borohydrides

Journal of the American Chemical Society, 1952
Discussion The metathetical reaction of alkali metal borohydrides with unsubstituted or partially substituted ammonium salts might be expected to yield ammonium borohydrides. This reaction, however, evidently gives other products, the nature of which leads in some cases to the supposition that while an ammonium borohydride may be formed momentarily, i ...
