On the reactions of chlorodithiophosphoric acid pyridiniumbetaine with polyfunctional nucleophiles. Part III: Reactions with monoalkylderivatives of thiosemicarbazide

Two heterocyclic compounds containing five-membered rings P-N-N-C-N were prepared from chlorodithiophosphoric acid pyridiniumbetaine, py · PS2Cl, and monosubstituted thiosemicarbazide derivatives RN(H)C(S)N(H)NH2, (R = methyl, ethyl). Both substances were completely characterized by 31P NMR, FT-IR, Raman spectroscopies and their molecular structures were determined by means of X-ray crystallography.
