A mixture of commercially available [Ru(cod)(η3-C4H7)2] and PCy3 reacts with H2 to give [RuH2(H2)2(PCy3)2] in high yields, whereas [RuCy2P(CH2)3PCy2}(η3-C4H7)2] leads to [Cy2P(CH2)3PCy2}RuH(µ-H)3Ru(H2)Cy2P(CH2)3PCy2}] under identical conditions; this new synthetic procedure provides convenient access to this type of ruthenium hydrides for investigation of their potential in catalytic reactions like the Murai-reaction.
商业上可获得的[Ru(cod)(η3-C4H7)2]与PCy3的混合物与H2反应,以高产率生成[RuH2(H2)2(PCy3)2],而在相同条件下,[RuCy2P(CH2)3PCy2}(η3-C4H7)2]则生成[Cy2P(CH2)3PCy2}RuH(μ-H)3Ru(H2)Cy2P(CH2)3PCy2}];这一新的合成方法为研究这类钌氢化合物在催化反应(如Murai反应)中的潜在应用提供了便捷途径。
