文摘

Well dispersed ruthenium(0) nanoparticles, stabilized in the ionic liquid agent, trihexyltetradecylphosphonium dodecylbenzenesulfonate, have been successfully prepared via a reduction reaction ofthe precursor [CpRuCp*RuCp*]PF₆ (Cp* = C₅Me₅). The ruthenium(0) nanoparticles were shown to catalyzethe isotope exchange reaction between ¹⁰B enriched diborane and natural abundant B₁₀H₁₄ to producehighly ¹⁰B enriched (~90%) decaborane(14) products. The ruthenium(0) nanoparticles were characterizedby TEM, XRD, and XPS. The ¹⁰B enriched decaborane(14) has been analyzed by Raman spectroscopy,NMR, and high-resolution MS.
