| Description | 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 4-phenyl-3-sulfido-3,5-dithioxo-1,2,4,3k5-triazaphospholidine (II) and 4-(4-nitrophenyl)-3-sulfido-3, 5-dithioxo-1,2,4,3k5-triazaphospholidine (III) were prepared. 31P NMR, FT-IR, Raman spectroscopy, and X-ray diffraction analysis revealed their molecular structures consisting of pyridinium cation and fivemembered P–N–N–C–N heterocyclic anion bearing relevant aryl group. |
