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

Reactions of chlorodithiophosphoric acid pyridiniumbetaine, py AE PS 2 Cl (I) with monosubstituted thiosemicarbazide derivatives RN(H)C(S)N(H)NH 2 , (R = methyl, ethyl), in acetonitrile media and in the presence of pyridine as an HCl acceptor were studied. New five-membered heterocyclic compounds were prepared, pyridinium salts of 4-methyl-3-sulfido-3,5-dithioxo-1,2,4,3k 5 -triazaphospholidine (II) and 4-ethyl-3-sulfido-3,5-dithioxo-1,2,4,3k 5 -triazaphospholidine (III). The substances II and III were completely characterized by 31 P NMR, FT-IR, Raman spectroscopies and their molecular structures were determined by the X-ray diffraction analysis.
