文摘Stable s-butyl n-heptafluorobutyryl nitroxide 3 has been generated in an electron transfer reaction in F113 ( CFCl2CF2Cl ) solution at r.t. The aN values for 3 in 11 aprotic solvents show a linear correlation with cybotactic solvent parameters ET and Z. The physical significance for slopes, slope×ET or slope×Z, and the extrapolated intercepts on the aN axis are well established. The plots of aN versus noncybotactic solvent parameters, such as dipolar moment and dielectric constant, are badly behaved.
