Synthesis of some new acyl pyrazolone type chelating agents |

| Abstract: | Eight new 1-phenyl-3-methyl-4-acyl-pyrazolones (1a-f, 2a, b) have been synthesized in good yield by reacting the corresponding acid halide with 1-phenyl-3-methyl-pyrazolone in dioxane in the presence of suspended Ca(OH)2 or Ba(OH)2, the products were identified by elemental analyses, IR, UV and 1H NMR spectra. Preliminary experiments indicate that all of their extraction efficiency for (UO2)2+ in chloroform-water are better than that of PMBP. The relative efficiency is found to be of the following order: 1b, 1d, 1f>1a, 1e>1c, 2a>2b>PMBP. |
