The reactions of 4‐substituted 3‐pyridinesulfonamides 1a, 1b, 1c, 1d, 1e with benzenesulfonyl chlorides 2a, 2b, 2c, 2d, 2e, 2f in acetonitrile were investigated. Depending on the structure of arylsulfonyl chlorides and the reaction conditions the following four types of products were obtained in good yields: 3‐sulfamoyl‐4‐R‐1‐arylpyridinium chlorides 3, 4, 5, 6, 7, 8; 1,10‐bis(3‐nitrobenzenesulfonylimino)deca‐2
研究了4-取代的3-吡啶磺酰胺1a,1b,1c,1d,1e与苯磺酰氯2a,2b,2c,2d,2e,2f在乙腈中的反应。取决于芳基磺酰氯和以良好的收率得到了以下四种类型的产品的反应条件的结构:3-氨磺酰基- 4- [R -1- arylpyridinium氯化物3,4,5,6,7,8; 1,10-双(3- nitrobenzenesulfonylimino)癸-2,4,6,8-四烯-2,9- disulfonamides 9,10,11,12 ; 1-取代的1,4-二氢-4-氧代-3- pyridinesulfonamides 13,14 ; 和4-甲氧基-3- [ N-(2,5-二氯苯基)磺酰基]磺酰胺化物15和16。讨论了这些反应的机理。
