Cesiumfluoroxysulfate was proved to be a N-fluorinating agent for some nitrogen compounds. Yields of products obtained mainly monofluoro-derivatives, depend on structures of initial nitrogen compounds. The ability of cesiumfluoroxysulfate for N-fluorination is much inferior to that of elemental fluorine and fluoromethylhypofluoride (CF3OF) but superior to that of perchlorylfluoride (FClO3).

A novel reaction scheme is presented for making a 3,3,7,7-tetrakis(difluoramino)octahydro-1,5-diazocinium salt, such as HNFX, from a tetrahydro-1,5-diazocine-3,7(2H,6H)-dione that does not employ N-nitrolysis,—but that instead requires protolytic N-deprotection, or protolytic denosylation, (i.e., the nosyl N-protecting group is replaced with protons, forming the corresponding protonated amine or ammonium derivative). In summary, the present method subjects a suitably N-protected dione to difluoramination followed by protolytic N-deprotection by addition of a superacid and subsequent nitration utilizing an electrophilic nitrating agent to yield the diazocinium salt.
