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
