| Description | To extend our previous study aimed at the reactions of chlorodithiophosphoric acid pyridiniumbetaine (py.PS2Cl) with thiosemicarbazide derivatives, we performed the reactions of chlorodithiophosphoric acid pyridiniumbetaine with a new group of polyfunctional nucleophiles - symmetrical and nonsymmetrical derivatives of hydrazine-1,2-bis(thiocarboamide) of general formula R(H)N-C(S)N(H)N(H)C(S)-N(H)R (R = methyl, i-propyl, ethyl, t-butyl, phenyl). In analogy to heterocyclic anions obtained with the thiosemicarbazide derivatives, the hydrazine derivatives were expected to form heterobicyclic dianions from the reactions with py.PS2CI. Four new compounds were prepared and characterized by P-31 NMR, FTIR, Raman spectroscopy, and single crystal X-ray diffraction. The molecular structure of the heterobicyclic dianion with unusual structural features was further examined by quantum chemistry calculations. |
