摘要
利用 4-酰代吡唑啉酮与氨基硫脲类化合物反应制备了新的吡唑啉酮类衍生物 ,并用IR ,NMR ,MS和元素分析进行表征 ,最后用X射线四圆衍射对其中的
Some new Compomds 1a (PMBP - tsc), 1b (PMBP - mtsc), 2a (PMAP - tsc), 2b (PMAP mtsc), 3a (PMCP - tsc), 3b ( PMCP - mtsc) have been synthesized by the reaction of 4 - acylpyrazolone with thiosemicarbazine or S - methyl - dithiocarbazate. The products were characterized by elemental analysis,IR, H-1 NMR and MS spectroscopy. The crystal structure of two compounds(la,3b) were determined by X - ray diffraction analysis.
