3 '-alkylsulfinyl-4-alkylthio and 3 ',4-di(alkylsulfinyl)-3,4 '-diquinolinyl sulfides

Reaction of 3',4-di(alkylthio)-3,4'-diquinolinyl sulfides 1 with nitrating mixture started with 3'-methylthio group monooxidation and yielded the 3'-alkylsulfinyl diquinolinyl sulfides 2 as the primary products. Further treatment of 2 with nitrating mixture proceeded as 4-alkylth...

Summary:Reaction of 3',4-di(alkylthio)-3,4'-diquinolinyl sulfides 1 with nitrating mixture started with 3'-methylthio group monooxidation and yielded the 3'-alkylsulfinyl diquinolinyl sulfides 2 as the primary products. Further treatment of 2 with nitrating mixture proceeded as 4-alkylthio group oxidation to give the mixture of disulfoxides 3 and 4, which underwent hydrolysis (in 90% sulfuric acid) to 3'-alkylsulfinyl-4(1H)-quinolinones 5.
