摘要

Abstract Aromatic nucleophilic substitution reaction of 1-fluoro-2, 4-dinitrobenzene with para- substituted and meta-substituted anilines was kinetically investigated in the mixtures of ethyl acetate and methanol at room temperature. The correlation of second-order rate coefficients with Hammett's substituent constants yields a fairly linear straight line with negative slope in different mole fractions of ethyl acetate–methanol mixtures. The measured rate coefficients ...
