Abstract
Reduction of ammonia borane, NH3·BH3, with Na or NaNH2 in refluxing tetrahydrofuran (thf) affords the new compound, the unsubstituted aminodiboranate Na(BH3−NH2−BH3) (1a). Similar N-alkyl- and N,N-dialkylaminodiboranate salts, Na(H3B−NHMe−BH3) (1b), Na(H3B−NHEt−BH3) (1c), Na(H3B−NMeEt−BH3) (1d), Na[H3B−N(C4H8)−BH3] (1e), and Na[H3B−N(C5H10)−BH3] (1f), where N(C4H8) = pyrrolido and N(C5H10) = piperido, have also been prepared, along with their adducts with dioxane Na[H3B−NRR′−BH3](diox) x where x = 0.5 or 1.0 (2a−f). Crystal structures of 2b, 2c, and 2e are reported. Treatment of ErCl3 with Na(H3B−NH2−BH3) in thf affords the new erbium complex Er(H3B−NH2−BH3)Cl2(thf)3, 3, which has been crystallographically characterized. 1H and 11B NMR spectra of the new compounds are reported.
