disulfonyl fluoride in not given SO2F2 and XeF2 were condensed onto S2NAsF6, mixt. was held at 0°C, with agitation, for 1h, 2 h at room temp.; volatiles were removed, products were not isolated; products were analized by IR;

disulfonyl fluoride in not given XeF2 was condensed onto a frozen mixure of S2NAsF6 and SO2F2, mixt. wasstirred and shaken for 0.5 h at 0°C, mixt. was stirred at room temp. for 12h; volatiles were removed, product was dissolved in SO2, than SO2 was removed , product was recrystd. from SO2-SO2ClF; elem. anal.;

disulfonyl fluoride in not given SO2F2 and F2 were added to S2NAsF6 at -196°C, mixt. was stirred for 4 h while held at -78°C, mixt. was stirred at room temp. for 20h; volatiles were removed, products were not isolated; products were analized by IR;

S2NAsF6 supported on Ni-crucibles reacted spontaneously with F2 at ca. 0.2 MPa; Products were condensed into a liquid-N2-cooled trap and after gasification expanded into a Monel cell. IR-spect. detn.;
