Kinetic Studies on the Reaction of Sulfinic Acids with Conjugated Alkenes, V: Kinetics of the Addition of Arenesulfinic Acids to 1-Aryl-1-arylsulfonyl2-nitroethenes

The addition of unsubstituted and substituted benzenesulfinic acids to 1-aryl-1-arylsulfonyl-2-nitroethenes has been studied kinetically by means of LC. The rection follows the second-order kinetics v = k [1-aryl-1-arylsulfonyl-2-nitroethene].[sulfinic acid]. The dependence of rate constants on the temperature and the influence of p-substituents on the kinetic parameters have been investigated. The activation energy and the enthalpy of the activation are calculated in the temperature range 288–308 K.
