在连二亚硫酸钠的存在下,用二硫化物实现了ISA酸酐与二硫化物的脱羧反应,从而以中等至极好的收率得到了S-芳基2-氨基苯甲硫酸酯衍生物。此外,还研究了二苯二硒化物与isatoic酸酐的脱羧作用。注意到使用四甲基秋兰姆二硫化物作为硫源获得了出人意料的2-(二甲氨基)-4 H-苯并[ d ] [1,3]噻嗪-4-酮。
The decarboxylation of isatoicanhydrides with disulfides was realized in the presence of sodium dithionite, leading to S-aryl 2-aminobenzothioate derivatives in moderate to excellent yields. Furthermore, the decarboxylation of diphenyldiselenide with isatoicanhydrides was also examined. It was noted that unexpected 2-(dimethylamino)-4H-benzo[d][1,3]thiazin-4-one was obtained using tetramethylthiuram
