Kinetic Studies on the Reaction of Sulfinic Acids with Conjugated Alkenes: IV. Kinetics of the Addition of Arenesulfinic Acids to 2-nitro-1-phenyl-1-phenylsulfonylethene

Abstract

The addition of unsubstituted and substituted benzenesulfinic acids to 2-nitro-1-phenyl-1-phenylsulfonylethene was studied kinetically by means of LC. The reaction follows the second-order kinetics: v = k[2-nitro-1-phenyl-1-phenylsulfonylethene] ·; [sulfinic acid]. The dependance of the rate constants on the temperature, and the influence of the p-substituents on the kinetic parameters were studied. The activation energy and the enthalpy of activation were calculated in the temperature range 288-308 K.
