Abstract
The rate constants for the reactions of 2-bromo-3-nitro-5-X-thiophens (X = H, Br, CONH2, CO2Me, Ac, SO2Me, CN, or NO2) with some substituted anilines YC6H4NH2(Y =p-OMe, p-Me, H, m-Cl, or p-CO2Me) have been measured in methanol at various temperatures. The sensitivity parameters, ρ(Y) and β(X), obtained from Hammett and Bronsted correlations are practically independent of the reactivity of the starting system. The relevance of these results to the reactivity–selectivity principle is discussed.
