摘要：
The interaction between unsubstituted and p-substituted benzenesulfinic acids and various 2-halogeno-7-nitroethenylarenes at mol ratios sulfinic acid:2-halogeno-2-nitroethenylarene = 1:1 and 2:1 was studied at 0 degrees C and 20 degrees C for 16 and 96 hours. It was proved that, depending on experimental conditions, the reaction results not only in alpha-halogeno-alpha-nitro-beta-sulfones but also in alpha-nitro-alpha,beta-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).
