method for the synthesis of 2,2′-diselenobis(benzenesulfonamides) 4 and 2-substituted 1,3,2-benzothiaselenazole 1,1-dioxides 2, has been elaborated. It is based on the conversion of 2-aminobenzenesulfonic acid into bis[2-(chlorosulfonyl)phenyl] diselenide (6), and reaction with ammonia or primary amines to give the sulfonamides 4. Finally, cyclization of these sulfonamides by oxidation with benzoyl peroxide
已经阐述了一种方便的合成2,2'-二硒双(苯磺酰胺)4和2-取代的1,3,2-苯并噻吩并噻吩并恶唑1,1-二氧化物2的方法。它基于2-氨基苯磺酸向双[2-(氯磺酰基)苯基]二硒化物(6)的转化,并与氨或伯胺反应生成磺酰胺4。最后,通过用过氧化苯甲酰氧化或通过用元素溴处理其钠盐或钾盐将这些磺酰胺环化,可生成1,3,2-噻吩并恶唑1,1-二氧化物2。
