Surface Interactions of Diborane
Diborane (B2H6) is a hydride gas often employed in high-purity industrial surface processes such as chemical vapor deposition or epitaxial layer growth. The use of diborane at industrial scales is complicated by the formation of higher-order borane contaminants in pure diborane gas via a complex …

Structure and dynamics of small clusters studied by microwave spectroscopy
… III reports on the discovery of tunneling in diborane-HCl. This tunneling only occurs in the isotopic species that are homonuclear with respect to the borons. DCl substitution also quenches the tunneling. This leads to the surprising conclusion that diborane subunit undergoes a geared motion …

Orientation Controllable Epitaxial Vapor-Liquid-Solid Semiconductor Nanowire Synthesis on Silicon Substrate
… of the catalyst size and additional diborane dopant gas flow. As the flow of impurity diborane is required at the beginning of synthesis, the modulation-doping method creates the vertically aligned silicon nanowire with less doped or intrinsic part in the stem structure. Third, …

An investigation into the synthesis and characterisation of metal borohydrides for hydrogen storage
… associated with the evolution of hydrogen and diborane. A composite mixture with magnesium hydride a reaction between diborane and magnesium hydride was observed form magnesium borohydride. Mechanical milling of calcium chloride or magnesium chloride with sodium borohydride did not produce …

Low-pressure chemical vapor deposition by thermolysis of disilane for low-temperature fabrication of pn junction solar cells
… of photovoltaic devices. Films doped with diborane showed high growth rates of approximately 45-150 Å/min for temperatures ranging from 450 to 550 °C. Undoped films were grown and found to have significantly lower growth rates and were not practical at temperatures less than 500 °C. The …

Reactivity of a Low Valent Gallium Compound
… forming gallium hydrazonides. Its reaction with diborane resulted in the formal nitrene insertion into the B-B bond to produce a gallium diborylamide. DFT calculations revealed intermediate gallium alkylidene formation from the reaction of NacNacGa with diazomethane that upon reaction with the …

Approaches to the synthesis of diazabiphenylenes
… 2,7]-dodecane, with diborane, the structures of which were established on the basis of their spectroscopic properties and also those of their N,N'-bis(4-nitrobenzoyl) derivatives. The N,N'-dibenzyl derivative of the latter dilactam was reduced with lithium aluminium …

Synthesis of novel pendant arm macrocyclic ligands as potential models for enterobactin
… followed by reduction of the amides with diborane. The mononuclear ferric complexes of compounds 34 and 36 Were prepared and characterized by uv-visible spectroscopy. Mononuclear nickel, cobalt, and copper complexes of these ligands were also characterized by uv-visible spectroscopy. The …

Volatile metal borohydride complexes: synthesis and characterization of new chemical vapor deposition precursors
… the addition of BH3•THF, which produced µ-aminodiborane. The µ-aminodiborane can then be ring opened with NaH, similar to what has been reported by Keller for the synthesis of sodium N,N-dimethylaminodiboranate. Implementing this method, the sterically bulky aminodiboranates: sodium …
