Reactions of carbonylchlorohydridobis(triisopropylphosphine)ruthenium with molecular hydrogen in solution. New molecular hydrogen complexes of ruthenium: RuH(H2)Cl(CO)[P(iso-Pr)3]2 and Ru(H)2(H2)(CO)[P(iso-Pr)3]2 (original) (raw)

Reactions of RuHCI(CO)[P(i-Pr),], with H2 in Solution. New Molecular Hydrogen Complexes of Ruthenium: RIIH(H~)CI(CO)[P(~-P~)~]~ and Ru(H)~(Hz)(Co)[P(i-Pr)J12 Reactions of dihydrogen with coordinatively unsaturated transition-metal hydride complexes containing Cl ligands lead, in some cases, to new classical and nonclassical hydrides. In solution, RuHC1(PPh3),,' OsHCl(C0) [P(i-Pr)3]2? and IrHC12L2 (L = P(i-Pr),, P C Y ,)~.~~ add H2, probably in an v2-fashion. The reactions of H2 with the monohydrides MHC12L2 (M = Rh, Ir) give also the dihydrides MH2C1L2,4 and IrH2ClL2 coordinates H2 to give Ir(H)2(H2)C1L2.4a-5 The polyhydrides R U H~(P P~~)~ and IrHsL2 are formed upon reaction of RUHCI(PP~,)~ and IrHC12L2 with dihydrogen in the presence of NaOHe6 In continuation of these studies we. have now found that RuHC1(CO)[P(i-Pr),l2 (1)' also reacts with H2 to form the new dihydrogen complexes
