  Compounds containing weak, non-covalent interactions to the metal in the backbone of 1,1′-bis(phosphino)metallocene ligands

  摘要：

  The reactions of Na[BArF] (BArF = tetrakis(3,5-bis(trifluoromethyl)phenyl)borate) with a series of [Pd(dpEMc)Cl-2] (dpEMc = 1,1'-bis(diphenylphosphino)ruthenocene (dppr), 1,1'-bis(diphenylphosphino)osmocene (dppo) or 1,1'-bis(diphenylarsino)ferrocene (dpaf)) compounds were examined. The reaction of Na[BArF] with [Pd(dppMc)Cl-2] (dppMc = dppr or dppo) resulted in the formation of the corresponding chloride-bridged dimers, [Pd(dppMc)(mu-Cl)](2)(2+), which were structurally characterized. However, these dimers appear to be unstable in CH2Cl2 and partially (Ru) or fully (Os) convert into the corresponding monomers, [Pd(dppMc)Cl](+), which are proposed to have a weak, non-covalent M-Pd (M = Ru or Os) interaction. Similar compounds, [Pd(dppo)PPh3](2+) and [Pt(dppMc)PPh3](2+) (M = Fe (1,1'-bis(diphenylphosphino)ferrocene (dppf)) or Os (dppo)), were also prepared and structurally characterized. These compound also exhibit weak, non-covalent M-Pd/Pt interactions. In addition, the electrochemical properties of these compounds were examined by cyclic voltammetry. (C) 2015 Elsevier Ltd.

  茂金属桥联双齿双膦配体的钯配合物：胺化和交叉偶联反应的合成，结构和催化活性

  摘要：

  报道了一系列新的茂金属桥联的二膦的合成，表征以及其中一些与Pd（II）的配合物的结构。在卤代芳烃的胺化反应和Suzuki反应中，将这些配合物作为催化剂进行了研究。基于钌茂茂（2）和渗透茂（3）的配合物在胺化反应中的活性比具有dppf的钯配合物低，而在Suzuki反应中则具有相同的活性。新钯络合物与二齿笨重和富电子的配体的Fe（η 5 -C 5 H ^ 4 P（ø -Pr我Ç 6 ħ 4）2）2（6）和Fe（η 5 -C 5 H ^ 4 P（ø -MeOC 6 ħ 4）2）2（5）显示出非常高的催化在胺化和铃木活性芳基溴化物的耦合。与配体6的配合物被伯胺和仲胺用于4-溴甲苯的胺化反应，并显示出优异的活性。

  The new ligand 1,1‘-bis(diphenylphosphino)osmocene (dppo) forms a variety of palladium(II) complexes showing either the κ2P,P or κ3Os,P,P bonding mode. The complex [Pd(OTs)(dppo)]OTs (OTs = p-toluenesulfonate) is an effective catalyst precursor for the selective methoxycarbonylation of ethylene to methyl propanoate and of styrene to a mixture of methyl 3-phenylpropanoate and methyl 2-phenylpropanoate
