1-苯基-3-甲基-4-酰基-5-吡唑酮是一类性能优良的β-二酮型螯合剂。这类化合物,特别是1-苯基-3-甲基-4-苯甲酰基-5-吡唑酮(PMBP)在金属离子的分析和分离工作中得到了广泛的应用。目前,合成这类化合物的新同系物并研究其性能已引起人们的注意。我们按Jensen法合成并鉴定了九个新的1-苯基-3-甲基-5-吡唑酮(PMP)的烷氧苯甲酰基衍生物1-9,其中1-5为C-酰化产物,6,7为O-酰化产物,8、9为二酰化产物。
1-phenyl-3-methyl-4-acyl-5-pyrazolone is a class of excellent β-diketone chelating agents. Such compounds, especially 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone (PMBP), have been widely used in the analysis and separation of metal ions. At present, the synthesis of new compounds of these compounds and study of its properties have attracted people’s attention. We synthesized and identified nine new 1-phenyl-3-methyl-5-pyrazolones (PMPs) of the alkoxybenzoyl derivatives 1-9 according to the Jensen method, where 1-5 is C-acyl 6,7 is O-acylated product, 8,9 is diacylated product.
