Pyrosulfonyldifluoride reacts with waterfree hydrazine in a molar ratio of 2 : 3 to give hydrazine -1,2-bis(sulfonylfluoride) in a low yield.. The reaction of N-fluorosulfonylamide and SOCl2 yields NH4⊕⊖ N(SO2F)2. This salt is converted to (C6H5)4P⊕⊖N(SO2F)2 in water by (C6H5)4PCl. (CH3)2NNH2 reacts with PSF3, PSF2Br, PSF2CH3 or PSF2C2H5 to yield the following compounds: (CH3)2NNHPSF2, (CH3)2NN (PSF2)2, (CH3)2NNHPSFCH3 and (CH3)2NNHPSFC2H5. The properties and the chemical behaviour of these substances are described. Results of ir-spectra, as well as 31P-, 19F- and 1H-nmr- and mass-spectra and elemental analysis characterize the compounds.
S4N3Cl reacts with sulfonic acids and imido- bissulfonyl derivatives under HCl-evolution to the following compounds: S4N3SO3CF3, S4N3N (SO2F)2, S4NSO3CH3HSO3CH3, S4N3N (SO2CF3) SO2Cl and S4N3N (SO2CF3) SO2F, They are yellow solids which decompose when heated below the melting point. The compounds are formed in nearly quantitative yield and have been characterized by elemental analysis, nmr and electronic spectra.
