On the reactions of chlorodithiophosphoric acid pyridiniumbetaine with polyfunctional nucleophiles. Part IV: Reactions with thiosemicarbazide monoaryl derivatives

Reactions of chlorodithiophosphoric acid pyridiniumbetaine with thiosemicarbazide monoaryl derivatives of general formula RN(H)C(S)N(H)NH2, (R = phenyl, 4-nitrophenyl) were studied. Syntheses were carried out in acetonitrile in the presence of pyridine as a HCl acceptor. Two new compounds with five-membered P-N-N-C-N heterocyclic anions were prepared and characterized.
