Abstract

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 ΔH# versus ΔS# for the reaction in DMSO and DMF gave good straight lines with isokinetic temperatures 128 C and 105 C, respectively. Good ...
