Abstract

The kinetics of the nitration of thiophene derivatives with nitric acid in acetic anhydride were investigated. The nitration of 2-substituted thiophenes is a second-order reaction. The rate constants and activation parameters of the reaction were calculated. The possibility of the use of the Hanmett and Yukawa-Tsuno equations for this reaction series is demonstrated. An isokinetic dependence is observed.
