Abstract
Abstract The relative mobilities of the nitro group and fluorine atom in 1, 3-dinitrobenzene and 1-fluoro-3-nitrobenzene by the action of phenols in the presence of potassium carbonate in dimethylformamide at 95–125° C were studied by the competing reaction method. The rate constant ratios k (NO 2)/k (F) were correlated with the differences between the corresponding activation parameters (ΔΔ H≠ and ΔΔ S≠). The greater mobility of the ...
