Three new Cu(ii) complexes, [Cu(4)(O)(L(n))(2)(CH(3)COO)(4)] where HL(1) = 4-methyl-2,6-bis(2-fluoroethyliminomethyl) phenol for complex , HL(2) = 4-methyl-2,6-bis(2-chloroethyliminomethyl) phenol for complex .0.25CH(3)CN and HL(3) = 4-methyl-2,6-bis(2-bromoethyliminomethyl) phenol for complex have been synthesized and characterized by elemental analysis, FTIR, UV-vis spectroscopy, and electrospray ionization mass spectroscopy. The structure of complex .0.25CH(3)CN has also been confirmed by single crystal X-ray diffraction analysis. These complexes have been found to be active catalysts for the oxidation of cyclohexane and toluene in the presence of hydrogen peroxide as the oxidant under mild conditions. Cyclohexane is oxidized to yield cyclohexanol and cyclohexanone, whereas toluene is oxidized to benzyl alcohol and benzaldehyde.
三种新的 Cu(ii) 配合物,[Cu(4)(O)(L(n))(2)(CH(3)COO)(4)],其中 HL(1) = 4-甲基-2,6-双(2-氟乙基亚氨基甲基)苯酚用于配合物 ,HL(2) = 4-甲基-2,6-双(2-氯乙基亚氨基甲基)苯酚用于配合物.0.25CH(3)CN,HL(3) = 4-甲基-2,6-双(2-溴乙基亚氨基甲基)苯酚用于配合物。通过元素分析、FTIR、UV-vis 光谱和电喷雾电离质谱对这些配合物进行了表征。配合物.0.25CH(3)CN 的结构也通过单晶 X 射线衍射分析得到了证实。这些配合物在温和条件下,以过氧化氢为氧化剂,被发现是环己烷和甲苯氧化的有效催化剂。环己烷氧化生成环己醇和环己酮,而甲苯氧化生成苄醇和苯甲醛。
