Abstract
The chlorine lability of the 2-nitrochlorobenzene derivative which con tains the superstrong electron-withdrawing substituent CF3S(O)=NSO2CF3 in position 4 has been compared with the analogous 4-trifluoromethyls ulphonyl derivative and picryl chloride in nucleophilic substitution. During interaction with hard nucleophilic agents, the effect of one su perstrong substituent approximately corresponds to the influence of tw o nitro groups in positions 2 and 4. With soft reagents, picryl chlori de is more active than the compound containing the CF3S(O)=NSO2CF3 gro up, polarizable only with difficulty.
