文摘

Reaction of the new precursor cis,trans-Ru(cod)(anln)₂Cl₂ with the diphosphine 1,2-bis(diphenylphosphino)-1,2-dicarba-closo-dodecaborane (o-dppc) unexpectedly results in two new ruthenium(II) hydrides, trans-Ru(o-dppc)₂(H)Cl and the neutral, five-coordinate complex Ru(o-dppc)(nido-dppc)(H), depending upon the reaction conditions [anln is aniline and nido-dppc is 7,8-(Ph₂P)₂C₂B₉H₁₀⁻]. Chloride abstraction from trans-Ru(o-dppc)₂(H)Cl leads to another five-coordinate hydride, [Ru(o-dppc)₂(H)]⁺, which is isolated as either a triflate or hexafluorophosphate salt. On the basis of labeling and reactivity studies, the source of the hydride appears to be the cod ligand.
