Reaction of hydrogen sulfate of 3,4-quinolinediyl bis-sulfides 1a, 2a, 3a, and 4a with isopropyl and cyclohexyl radicals formed from alkyl iodide/hydrogen peroxide/DMSO/Fe++ salt system took place at α-quinolinyl position and led to the respective mono- and dialkyl derivatives 1b-e, 2b-e, 3b,c, and 4b,c. Action of sodium methoxide towards isopropyl derivatives 1b,c and 2b,c caused the 1,4-dithiin ring
3,4-喹啉二基双硫化物1a,2a,3a和4a的硫酸氢与由烷基碘化物/过氧化氢/ DMSO / Fe ++盐体系形成的异丙基和环己基反应在α-喹啉基位置发生并引发分别对应于单和二烷基衍生物1b-e,2b-e,3b,c和4b,c。甲醇钠对异丙基衍生物1b,c和2b,c的作用导致1,4-二硫辛开环形成(在S-甲基化后)3,4'-和3,3'-二喹啉基硫化物6a,b和3,4'-的衍生物。7a,b。
