【Abstract】 It has been found that polyfluoroalkylthioether 2 might rearrange spotaneously to isomeric products 4 at r. t. to 70℃. In this paper, we studied the rearrangement process of polyfluoroalkylthioether by crossing reaction, solvent effects, the change of reactant concentration, trapping experiment, measuring rates and the activation energy(E_a), activation enthalpy (△H~≠), entropy (△S~≠) of the reaction according to Arrhenius equation. The reaction might occur via an intramolecular nucleophilic rearrangement process.更多还原
