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 NH4āā N(SO2F)2. This salt is converted to (C6H5)4PāāN(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.
