Abstract

The kinetics of the reaction of substituted anilines with 2‐chloro‐5‐nitropyridine were studied in dimethyl sulfonide (DMSO) and dimethyl formamide (DMF) at different amine concentrations and temperatures in the range 45–60°C. In both solvents the reaction was not a base‐catalyzed one. A plot of Δ__H__^#^ versus Δ__S__^#^ for the reaction in DMSO and DMF gave good straight lines with isokinetic temperatures 128°C and 105°C, respectively. Good linear relationships were obtained from the plots of log k~1~ against σ° values at all temperatures with negative ρ values (−1.63 to −1.28 in DMSO) and (−1.26 to −0.90 in DMF). © 2002 Wiley Periodicals, Inc.
