N,N'-二(芳磺酰) 亚磺酰胺-S-(2-苯并咪唑基) 类化合物的合成

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％.

Synthesis of N,N'-di(arylsulfonyl) sulfenamide-S-(2- benzimidazolyl) compounds

Synthesis of N,N'-di(benzoylsulfonyl) sulfenamide-S-(2- benzimidazolyl) sidium(a), N,N'-di(p-toluylsulfonyl) sulfenamide-S-(2-benzimidazolyl) sodium(b), N,N'-di(p- chlorobenzolsulfonyl) sulfenamide-S-(2-benzimidazolyl) sodium(c), N,N'-di(m-nitrobenzoylsulfonyl) sulfenamide-S-(2- benzimidazolyl) sodium(d) and N,N'-di(p-methoxybenzoylsul- fonyl) 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'-di(p-chlorobenzolsulfonyl) sulfenamide-S-(benzimidazolyl) (h), N,N'-di(m-nitrobenzoylsulfonyl) sulfenamide-S-(benzimidaz- olyl) (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.
