| Description | Chlorodithiophosphoric acid pyridiniumbetaine, PyPS2Cl (I), reacts with thiosemicarbazide derivatives (RNH)(H2N-Me)CS, R= iso-propyl, tert.-butyl, in acetonitrile in absence of any HCl-acceptor to new compounds with five-membered heterocycle, i.e. 5-iso-propylamino-4-methyl-2-sulfido-2-thioxo-1,3,4,2?5-thiadiazaphospholan-5-onium (II) or 5-tert.-butylamino-4-methyl-2-sulfido-2-thioxo-1,3,4,2?5-thiadiazaphospholan-5-onium (III). The triethylammonium salt of 1,3-bis-(N-methyl-N'-tert.-butyl-thioureido)-2,4-disulfido-2,4-dithioxo-1,3-diaza-2?5,4?5-diphosphetidine (IV) is formed when the reaction is carried out in the presence of triethylamine. The prepared compounds were characterised by 31P-NMR, FT-IR spectroscopies, mass spectrometry, and the molecular structures of II, III, and IV were determined by X-ray crystallography. |
