On the route to the N-phosphoryl sulfamic acid
Mielniczak,Lopusinski
, p. 785 - 791 (2007/10/03)
Synthesis of the previously unknown N-diethyl phosphorosulfamate 15 was accomplished by direct sulfamation of diethyl phosphoroamidate 4 with sulfur trioxide-DMF complex 14. The acid 15 was isolated in form of benzyl-16 and cyclohexylammonium 17 salts, which were found to be unstable in water solution. The other possible routes to sulfamate 15 were briefly tested.
