β—二酮是一类用途广泛的螯合剂 ,它与稀土元素的络合性能等已有大量报道 [1～ 5]。自 1 95 9年Jensen[6]首次合成了 1—苯基— 3—甲基— 4—苯甲酰基— 5—吡唑酮并初步研究了它对金属离子的螯合作用后 ,β—二酮类配合物得到了国内外的广泛关注 [7]。本文以 1—苯基— 3—
β-diketone is a kind of chelating agent with a wide range of uses. It has been widely reported that it has complexation with rare earth elements [1-5]. Since 1995, Jensen [6] synthesized 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone for the first time and studied its chelating effect on metal ions. Ketones have received widespread attention at home and abroad [7]. In this paper, 1-phenyl-3-
