惰性碳氢化合物的C-H活化：在牺牲氧化剂间氯过苯甲酸存在下，新型钴、镍和铜配合物与三足4N配体Me6TREN(三[2-（二甲氨基）乙基]胺及相关化合物作为环己烷和金刚烷部分氧化的均相催化剂进行了测试。M = Co、Ni或Cu与三足氮配体的新型[M(L)(CH3COO)][PF6]配合物的表征[j]环己烷和金刚烷在均相溶液中的催化部分氧化间氯过苯甲酸作为氧化剂时的周转率和选择性的测定。采用简单的两步法合成了四种新化合物[M(L)(CH3COO)][PF6]，其中L为四齿三足配体，如tris[2-（二甲氨基）乙基]胺（L1）或（2-氨基乙基）双（2-吡啶基甲基）胺（L2）， M为Co(II), Ni（II）或Cu（II）。这些化合物已通过元素分析、质谱、红外光谱和x射线衍射进行了表征。研究了含有脂肪族配体L1的衍生物在牺牲氧化剂m-CPBA（间氯过苯甲酸）存在下对环己烷和金刚烷氧化的催化性能。对钴和镍化合物确定了良好的吨和选择性。
C-H activation of inert hydrocarbons: New cobalt, nickel and copper complexes with the tripodal 4N ligand Me6TREN (tris[2-(dimethylamino)ethyl]amine and related compounds are tested as homogeneous catalysts for the partial oxidation of cyclohexane and adamantane in the presence of the sacrificial oxidant m-chloroperbenzoic acid. Characterization of new [M(L)(CH3COO)][PF6] complexes with M = Co, Ni or Cu and tripodal nitrogen ligands L. Catalytic partial oxidation of cyclohexane and adamantane in homogeneous solution. Determination of turnovers and selectivities in the presence of m-chloroperbenzoic acid as the oxidant. Four new compounds of the general formula [M(L)(CH3COO)][PF6], where L is a tetradentate tripodal ligand such as tris[2-(dimethylamino)ethyl]amine (L1) or (2-aminoethyl)bis(2-pyridylmethyl)amine (L2) and M is Co(II), Ni(II) or Cu(II), have been prepared employing a simple two-step synthesis. The compounds have been characterised by elemental analysis, mass spectroscopy, IR spectroscopy and X-ray diffraction. The catalytic properties of the derivatives containing the aliphatic ligand L1 have been investigated in particular toward the oxidation of cyclohexane and adamantane in the presence of the sacrificial oxidant m-CPBA (meta-chloroperbenzoic acid). Good TONs and selectivity have been determined for the cobalt and nickel compounds.
