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 a

The interaction between unsubstituted and p-substituted benzenesulfinic acids and various 2-halogeno-2-nitroethenylarenes at mol ratios sulfinic acid:2-halogeno-2-nitroethenylarene = 1:1 and 2:1 was studied at 0 deg C and 20 deg C for 16 and 96 hours.It was proved that, depending on experimental conditions, the reaction results not only in α-halogeno-α-nitro-β-sulfones but also in α-nitro-α,β-disulfones, which are obtained by a consecutive process.The quantitative ratio of these products and the isomer composition of some of them were determined by using high-performance liquid chromatography (HPLC). - Keywords: Sulfinic acids, 2-halogeno-2-nitroethenylarenes, HPLC, α-halogeno-α-nitro-β-nitro-β-sulfones, α-nitro-α,β-disulfones, α-diastereomers.
