A new aspect on the hydrogen release from NH 3BH 3 using a homogeneous ruthenium catalyst was presented. The boron NMR results of the ruthenium (Ru(DMSO) 4Cl 2) catalyzed reaction of NH 3BH 3 in methanol at room temperature showed that the boron cleanly and quickly converted from BH 3 attached to NH 3 to methylborate. During the catalysis, the Ru(DMSO) 4Cl 2 complex was completely converted to a new soluble catalytic species, which did not contain any Ru-S or Ru-Cl bonds. The metal-containing catalytic species (or its resting state) only had light element (O, B, or N) ligands directly bound to the ruthenium. The boron-containing reaction products were dependent upon the solvent and the reaction conditions. Efficient release of H 2 from NH 3BH 3 was shown. This is an abstract of a paper presented in the ACS Fuel Chemistry Meeting Fall 2005 (Washington, DC Fall 2005).
