在温和条件下,在1-辛烯氧化反应中,研究了酞菁铁、钴N-碱加合物的催化作用.发现在室温和0.1MPa的氧气氛中,在共催化剂存在时,酞菁铁、钴N-碱加合物确实具有催化分子氧活化和使其转移至烯烃的功能.酞菁铁N-碱加合物的催化活性总是高于酞菁钴的.同时,在同一中心金属离子的情况下,N-碱配体性质对催化活性有明显影响,其活性序列如下:PcM(pip)_2>PcM(Py)_2>PcM(γ-picol)_2≈PcM(N-MeIm)_2.
Catalytic activity of iron phthalocyanine and cobalt N-base adducts was studied under mild conditions in the 1-octene oxidation reaction and found that at room temperature and 0.1 MPa of oxygen in the presence of a co-catalyst, phthalocyanine Iron and cobalt N-base adducts do have the function of catalyzing molecular oxygen activation and transferring it to olefins.The catalytic activity of iron phthalocyanine N-base adduct is always higher than that of cobalt phthalocyanine.At the same time, In the case of metal ions, the properties of the N-base ligand have a significant influence on the catalytic activity. The active sequences are as follows: PcM (pip) 2> PcM (Py) _2.
