Abstract: The rate of rearrangement of 8 I (X = MeO, Me, H, NHAc, I, Cl, Br, NO2) to the corresponding II in MeOH in the presence of MeONa was detd. via spectra. The rate consts. (log k') obtained by extrapolation of the dependence of the 2nd order rate consts. on MeO-concn. down to 0 concn. were correlated with σ substituent consts. The correlation for I of log k' = 2.155 and σ = -2.192 approxd. the correlation of log k' = 1.886 and σ = -2.321 for III.
