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。
