N-PENTAFLUOROSULFANYL-N-NITRO CARBAMATES
Sitzmann, Michael E.
, p. 195 - 207 (2007/10/02)
Unlike N-alkyl carbamates, N-pentafluorosulfanyl carbamates (SF5NHCO2R) did not readily undergo nitration to provide the N-NO2 derivatives.Although trifluoroacetyl nitrate did provide nitration, work-up yielded a mixture of SF5N(NO2)CO2R and starting mate
