In connection with our previous research, reactions of chlorodithiophosphoric acid pyridiniumbetaine, py.PS2Cl (I), with monoaryl thiosemicarbazide derivatives RN(H)C(S)N(H)NH2, (R = phenyl, 4-nitrophenyl) were studied with the aim to prepare new heterocyclic compounds. All reactions were carried out in acetonitrile in the presence of pyridine as an HCl acceptor. New compounds, pyridinium salts of
结合我们先前的研究,研究了氯二硫代磷酸吡啶甜菜碱py.PS2Cl(I)与单芳基硫代氨基脲衍生物RN(H)C(S)N(H)NH2(R =苯基,4-硝基苯基)的反应。目的是制备新的杂环化合物。所有反应均在乙腈中在吡啶作为HCl受体的存在下进行。新化合物,4-苯基-3-硫代-3,5-二硫代-1,2,4,3k5-三氮杂磷腈(II)和4-(4-硝基苯基)-3-硫代-3,5-二硫代的吡啶鎓盐制备了-1、2、4、3k5-三氮杂膦酰基(III)。31 P NMR,FT-IR,拉曼光谱和X射线衍射分析显示它们的分子结构由吡啶鎓阳离子和带有相关芳基的五元P–N–N–C–N杂环阴离子组成。
