The reduction of dichlorotris(triphenylphosphine)ruthenium(II) in tetrahydrofuran–acetonitrile by sodium or magnesium amalgam produces a compound shown to be a hydrido ortho-metallated phosphine ruthenium(II) complex RuH(C6H4PPh2)(MeCN)(PPh3)2. This compound has all the characteristics of a complex previously reported and alleged to be a ruthenium(0) complex containing a π-bonded acetonitrile ‘Ru(MeCN)(PPh3)4·MeCN’
钠或镁汞齐还原四氢呋喃-乙腈中的二氯三(三苯基膦)钌(II),生成的化合物显示为氢化邻位金属化的膦钌(II)络合物RuH(C 6 H 4 PPh 2)(MeCN)( PPh 3)2。该化合物具有先前报道的据称是钌(0)配合物的所有特征,该配合物包含π键联的乙腈'Ru(MeCN)(PPh 3)4 ·MeCN'。
