• Synthesis and unexpected reactivity of [Ru(η 6-cymene)Cl2(PPh2Cl)], leading to [Ru(η 6-cymene)Cl2(PPh2H)] and [Ru(η 6-cymene)Cl 2 (PPh2OH)] complexes

  The reaction of [Ru(η 6-cymene)Cl2]2 and PPh2Cl in the ratio 1:2 gives a stable [Ru(η 6-cymene) Cl2(PPh2Cl)] complex. Attempts to make the cationic [Ru(η 6-cymene)Cl(PPh2Cl)2]Cl with excess PPh2Cl and higher temperatures led to adventitious hydrolysis and formation of [Ru(η 6-cymene)Cl2(PPh2OH)]. Attempts to make a phosphinite complex by reacting [Ru(η 6-cymene)Cl2]2 with PPh2Cl in the presence of an alcohol results in the reduction of PPh2Cl to give [Ru(η 6-cymene)Cl2(PPh2H)] and the expected phosphinite. The yield of the hydride complex is highest when the alcohol is 1-phenyl-ethane-1,2-diol. All three half-sandwich complexes are characterized by X-ray crystallography. Surprisingly, the conversion of chlorodiphenylphosphine to diphenylphosphine is mediated by 1-phenyl-ethane-1,2-diol even in the absence of the ruthenium half-sandwich precursor.

  Ru(η 6-氰基)Cl2]2和PPh2Cl以1:2的比例反应生成稳定的[Ru(η 6-氰基)Cl2(PPh2Cl)]络合物。尝试用过量的 PPh2Cl 和更高的温度来制造阳离子 [Ru(η-6-亚甲基)Cl(PPh2Cl)2]Cl，会导致偶然的水解并形成 [Ru(η-6-亚甲基)Cl2(PPh2OH)]。试图通过[Ru(η 6-亚甲基)Cl2]2 与 PPh2Cl 在醇的存在下反应来制造膦络合物，结果 PPh2Cl 被还原，生成[Ru(η 6-亚甲基)Cl2(PPh2H)]和预期的膦。当醇为 1-苯基-1,2-乙二醇时，氢化物络合物的产率最高。所有这三种半夹心复合物都具有 X 射线晶体学特征。令人惊讶的是，即使在没有钌半三明治前体的情况下，氯二苯基膦向二苯基膦的转化也是由 1-苯基-1,2-乙二醇介导的。

  PhL1, PhL2, and PhL4, and [RuCl(μ-Cl)(η6-Me2CHC6H4Me)]2 in CH2Cl2 affords the P/P-bridging dinuclear ruthenium(II) complexes RuCl2(η6-Me2CHC6H4Me)}2(μ-CyL1−PhL4) 1a−f as red/orange solids. Careful monitoring by 31P1H} NMR spectroscopy of CDCl3 solutions of 1a−e revealed remarkably clean P−Csp3 bond cleavage to give RuII mononuclear species 2a−e and the known secondary phosphine complexes RuCl2(η6-Me2CHC6H4Me)(PCy2H)

  The [RuCl2(eta(6)-arene)](2) complex reacts with PPh2R (R = H, Py, CH2Py, C=CPh, C=C'Bu and C=Cp-Tol) ligands in CH2Cl2 to give neutral P-coordinated ruthenium(II) complexes [RuCl2(p-cymene)PPh2R]. The structure of [RuCl2(p-cymene)PPh2H] and [RuCl2(p-cymene)PPh2Py] complexes has been established by X-ray diffraction. The neutral P-coordinated complexes [RuCl2(p-cymene)PPh2Py] and [RuCl2(p-cymene)PPh2CH2Py] react with NaBF4 in CH2Cl2-MeOH mixture to give [RuCl(eta(6)-p-cymene)PPh2Py]BF4 and [RuCl(eta(6)-p-cymene)PPh2CH2Py]BF4 complexes, in which PPh2Py and PPh2CH2Py act as bidentate ligands. The structure of [RuCl(eta(6)-p-cymene)PPh2Py]BF4 was determined by X-ray diffraction. The reaction of [RuCl2(eta(6)-arene)](2) with PPh2C=CPPh2 led to the [RuCl2(p-cymene)](2)PPh2C=CPPh2 complex, in which the diphosphine ligand bridges two [RuCl2(p-cymene)] units. [RuCl2(p-cymene)PPh2Py] and [RuCl(eta(6)-p-cymene)PPh2Py]BF4 are suitable catalyst precursors for the hydrogenation of styrene and phenylacetylene. (C) 1998 Elsevier Science S.A. All rights reserved.
