The kinetics of the reactions of 2-(acetylamino)ethyl 2,6-dinitrophenyl ether (Smiles rearrangement) and N-acetyl-N-(2-hydroxyethyl)-2,6-dinitroaniline with sodium isopropoxide in the DMSO–2-propanol mixture (20 : 80 v/v) was studied. Both reactions were found to rapidly produce the same spiro anionic σ complex, giving N-(2-acetoxyethyl)-2,6-dinitroaniline. Although the rates for formation of the complex
