Reaction of 4-methoxy-3'-alkylthio-3,4'-diquinolinyl sulfides 1a-d with a nitrating mixture led to the title sulfoxides 2a-d , but the same treatment of isopropylthio derivative 1e resulted in S-dealkylation and oxidation with formation of 3,3'-diquinolinyl disulfide 3 . 3'-Alkylsulfinyl group promotes nucleophilic methoxy-desulfidation of 4'-quinolinyl sulfur bond in sulfoxides 2 , as compared to
4-甲氧基-3'-烷硫基-3,4'-二喹啉基硫化物 1a-d 与硝化混合物的反应产生标题亚砜 2a-d,但对异丙硫基衍生物 1e 的相同处理导致 S-脱烷基化和氧化3,3'-二喹啉二硫化物 3 的形成。与硫化物 1 中的相比,3'-烷基亚磺酰基促进亚砜 2 中 4'-喹啉基硫键的亲核甲氧基脱硫,在这种情况下,它产生 3-喹啉基亚砜 6 和 3-喹啉硫醇盐 4-A。
