Regeneration of Ammonia Borane Spent Fuel by Direct Reaction with Hydrazine and Liquid Ammonia
A method to regenerate lightweight, hydrogen-rich ammonia borane improves its prospects as a vehicular fuel source. Ammonia borane (H3N-BH3, AB) is a lightweight material containing a high density ofExpand
The hydrodeoxygenation of bioderived furans into alkanes.
The conversion of biomass into fuels and chemical feedstocks is one part of a drive to reduce the world's dependence on crude oil. For transportation fuels in particular, wholesale replacement of aExpand
Regeneration of Ammonia Borane Spent Fuel by Direct Reaction with Hydrazine and Liquid Ammonia.
Polyborazylene which is formed by removal of more than two equivalents of H2 per molecule from NH3·BH3 is converted back to ammonia borane nearly quantitatively by a 24-hour treatment with N2H4 inExpand
Synthesis of a Stable Compound with Fivefold Bonding Between Two Chromium(I) Centers
Although in principle transition metals can form bonds with six shared electron pairs, only quadruply bonded compounds can be isolated as stable species at room temperature. Here we show that theExpand
Substituent effects in formally quintuple-bonded ArCrCrAr compounds (Ar = terphenyl) and related species.
The effects of different terphenyl ligand substituents on the quintuple Cr-Cr bonding in arylchromium(I) dimers stabilized by bulky terphenyl ligands (Ar) were investigated. A series of complexes,Expand
Aerobic oxidation of pinacol by vanadium(V) dipicolinate complexes: evidence for reduction to vanadium(III).
The reactivity of vanadium complexes bearing the ligand dipicolinic acid (H(2)dipic) with alcohols has been explored. Dipic vanadium complexes are able to catalyze the aerobic oxidative C-C bondExpand
Recycle of tin thiolate compounds relevant to ammonia-borane regeneration.
The use of benzenedithiol as a digestant for ammonia-borane spent fuel has been shown to result in tin thiolate compounds which we demonstrate can be recycled, yielding Bu(3)SnH andExpand
Synthesis and characterization of low-coordinate divalent aryl transition-metal halide analogues of grignard reagents: precursors for reduction to metal-metal-bonded complexes.
The synthesis and characterization of the series of divalent first-row aryl transition-metal(II) halide compounds [Cr(mu-Cl)Ar']2 (1) and (Li(OEt2)Ar'MI2]2 (M=Mn (2), Fe (3), and Co (4);Expand
Ni(bpy)(cod): A Convenient Entryway into the Efficient Hydroboration of Ketones, Aldehydes, and Imines
The catalytic hydroboration of ketones, aldehydes, and imines with pinacol borane and Ni(bpy)(cod) has been demonstrated in benzene at room temperature and low catalyst loadings (0.03–0.3 mol-%).Expand
Spectroscopic evidence for the direct coordination of the pertechnetate anion to the uranyl cation in [UO2(TcO4)(DPPMO2)2]+.
We report the synthesis and structural characterization of [UO(2)(ReO(4))(DPPMO(2))(2)][ReO(4)] and [UO(2)(Cl)(DPPMO(2))(2)][Cl] (where DPPMO(2) = bis(diphenylphosphino)methane dioxide). In bothExpand
