制备了一系列含三脚架配体tmpa,Me 2uns-penp,Me 4apme和Me 6 tren的铬(II)配合物,并研究了它们对分子氧的反应性。对配合物[Cr(Me 2uns-penp)Cl]2(BPh 4)2、[Cr(Me 6 tren)Cl]Cl、[Cr(Me 4apme)Cl] BPh 4和[Cr(Me 4ampe)Cl 3]进行了结构表征。配合物显示与分子氧的反应,但不可能表征这些反应的中间体。研究了配合物对甲苯等有机底物的氧化行为,并观察了甲苯氧化为苯甲醛的反应。
A series of chromium(II) complexes containing the tripodal ligands tmpa, Me2uns-penp, Me4apme and Me6tren were prepared and investigated with regard to their reactivity towards dioxygen. It was possible to structurally characterize the complexes [Cr(Me2uns-penp)Cl]2(BPh4)2, [Cr(Me6tren)Cl]Cl, [Cr(Me4apme)Cl]BPh4 and [Cr(Me4ampe)Cl3]. The complexes show reactions with dioxygen, but it was not possible to characterize intermediates of these reactions. The oxidation behavior of the complexes towards organic substrates like toluene was investigated and oxidation of toluene to benzaldehyde was observed.
