Catalytic Dehydrogenation of Amine‐Boranes using Geminal Phosphino‐Boranes [PDF]
The reaction of the intramolecular frustrated Lewis pair (FLP) tBu2PCH2BPh2 with the amine‐boranes NH3·BH3 and Me2NH·BH3 leads to the formation of the corresponding FLP‐H2 adducts as well as novel five‐membered heterocycles that result from capturing the in situ formed amino‐borane by a second equivalent of FLP.

Transformation of struvite from wastewater to a hydrogen fuel storage compound ammonia borane
Ammonia borane (NH3BH3) is a carrier of hydrogen gas that is known as a carbon-free renewable energy source. A high hydrogen content of ammonia borane and its stability in air at ambient temperatures make it a valuable molecule for its potential use as a

Synthesis of six-membered silacycles by borane-catalyzed double sila-Friedel–Crafts reaction
We have developed a catalytic synthetic method to prepare phenoxasilins. A borane-catalyzed double sila-Friedel–Crafts reaction between amino group-containing diaryl ethers and dihydrosilanes can be used to prepare a variety of phenoxasilin derivatives ...

Crystal structure of borated N,N,N′,N′-tetramethyldiaminomethane
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.
