General Description

Hexamethylborazine is a chemical compound with the formula B3N3H6(CH3)6. It is a colorless liquid at room temperature and is highly flammable. Hexamethylborazine is primarily used as a high-energy fuel for propulsion systems, such as in rocket engines. It has a high energy density and is capable of releasing a large amount of energy upon combustion, making it suitable for high-performance applications. Additionally, it has been studied for its potential use in boron nitride thin film deposition and as a precursor for boron nitride ceramics, which have high-temperature stability and exceptional mechanical properties. However, hexamethylborazine is also known to be toxic and harmful if ingested or inhaled, and thus requires proper handling and safety precautions in its use.

Recyclable Trifluoromethylation Reagents from Fluoroform

We present a strategy to rationally prepare CF3- transfer reagents at ambient temperature from HCF3. We demonstrate that a highly reactive CF3- adduct can be synthesized from alkali metal hydride, HCF3, and borazine Lewis acids in quantitative yield at room temperature. These nucleophilic reagents transfer CF3- to substrates without additional chemical activation, and after CF3 transfer, the free borazine is quantitatively regenerated. These features enable syntheses of popular nucleophilic, radical, and electrophilic trifluoromethylation reagents with complete recycling of the borazine Lewis acid.

B-methyl amine borane derivatives: Synthesis, characterization, and hydrogen release

We describe the synthesis of MeH2N-BH2Me (3) and H3N-BH2Me (4) as potential hydrogen storage materials with 6.8wt-% and 8.9wt-% capacity, respectively. Compounds 3 and 4 readily release 2 equivalents of H2 at 80°C in the presence of a CoCl2 catalyst to furnish the corresponding trimerized borazine derivatives. Regeneration of 3 from its spent fuel material can be accomplished using a simple two-step process: activation with formic acid followed by reduction with LiAlH4. CSIRO 2014.
