A number of poly- or perfluoroalkyl t-butyl nitroxides RFN(Oo)tBu have been generated by a new method which makes use of the electron- transfer initiated reaction between polyfluoroalkyl iodides and various electron donors, i.e., MNO2, CH2NO2Na, MeCHNO2Na, Me2CNO2Na and Na2S2O4, in the presence of 2-methyl-2-nitrosopropane. Substituent effects on the hyperfine coupling constants aN and aβF values are
