Synthetic studies of sodium aminodiboranate salts with electronwithdrawing substituents
… 1, we describe the synthesis of three new sodium aminodiboranate salts, Na(BH3)2NRR′, with trimethylsilyl groups on nitrogen. These compounds – sodium N,N-bis-(trimethylsilyl)¬aminodiboranate, sodium N-trimethylsilylamino¬diboranate, and sodium N-methyl-N-trimethylsilylaminodiboranate – were …

Aminodiboranates: syntheses, structures, and applications for chemical vapor deposition
… ThCl₄ with 4 equivalents of sodium N,N-dimethylaminodiboranate, Na(H₃BNMe₂BH₃), in tetrahydrofuran produces the new complex Th(H₃BNMe₂BH₃)₄. The thorium center forms bonds with fifteen hydrogen atoms; accordingly, this is the first example of a fifteen-coordinate atom of any kind. As determined …

Divalent transition metal centers: the synthesis of new chemical vapor deposition precursors and studies of ethylene polymerization and oligomerization catalysts
… of the chelating borohydride, N,N-dimethylaminodiboranate (DMADB). To date, attempts to synthesize homoleptic complexes of the late transition metals have afforded intractable mixtures, likely the result of overreduction of the metal center. This work has focused on the synthesis and …

Chemical approaches to the improved performance of nanoelectronic devices
… a series of lanthanide tris(N,N-dimethylaminodiboranate) (Ln(dmadb)3) complexes and demonstrated their utilization as Ln2O3 CVD precursors. The mechanism of the salt elimination reaction that generates Nd(dmadb)3 was examined by 11B NMR spectroscopy. We found that the treatment of NdCl3 …
