【摘要】 <正> 本文报道了新化合物N,N＇—二(芳磺酰)亚磺酰胺—S—(2—苯并咪唑基)钠(a～e)以及N,N＇—二(芳磺酰)亚磺酰胺—S—(2—苯并咪唑基)(f～i)的合成。通过在感光乳剂中的应用,我们发现a,b和c具有超增感作用,它们分别使卤化银乳剂的感光度提高62％,22％和45％。 钠—N—氯芳磺酰亚胺化合物既是一类精细化工产品,又是一类重要的反应中间体。由它们更多还原

【Abstract】 Synthesis of N, N’-di(benzoylsulfonyl) sulfenamide-S-(2-benzimidazolyl)sodium(a), N, N’-di(p -toluylsulfonyl)sulfenamide-S-(2-benzimidazolyl) sodium(b), N, N’-di(p-chlorobenzolsulfonyl)sulfena-mide-S-(2-benzimidazolyl)sodium(c), N, N’-(m-nitrobenzoybulfonyl)sulfenamide-S-(2-benzimidazolyl) sodium(d) and N, N’-di(p-methoxybenzoylsulfonyl)sulfenamide-S-(2-benzimidazolyl)sodium (e) were reported, N, N’-di(benzoylsulfonyl)sulfenamide-S-2-(benzimidazolyl) (f), N, N’-di(p-toluylsulfonyl) sulfenamide-S-(benzimidazolyl) (g), N, N’-(p-chlorobenzolsulfonyl)sulfenamide-S-(benzimidazolyl) (h), N, N’-di(m-nitrobenzoybulfonyl)sulfenamide-S-(benzirnidazolyl) (i) were also reported. The optical sensitization have been determined in photographic emulsion, it shows that a, b and c can be used as supersensitizer, they increase the sensitiveness 62%, 22% and 45% respectively.更多还原
