Abstract (E)-2,2,5,5-Tetramethyl-3,4-diphenylhex-3-ene does not iodinate under normal conditions. Silver trifluoromethanesulfonate catalysis of the silver sulfate/iodine promoted reaction is shown to add versatility to this reation and successfully produce (E)-3-(4'-iodophenyl)-2,2,5,5-tetramethyl-4-phenylhex-3-ene and (E)-2,2,5,5-tetramethyl-3,4-di(4'-iodophenyl)hex-3-ene in good yield under mild
摘要 (E)-2,2,5,5-Tetramethyl-3,4-diphenylhex-3-ene 在正常条件下不会发生碘化。硫酸银/碘促进反应的三氟甲磺酸银催化显示为该反应增加了多功能性,并成功地生产 (E)-3-(4'-碘苯基)-2,2,5,5-四甲基-4-苯基己基-3 -ene 和 (E)-2,2,5,5-tetramethyl-3,4-di(4'-iodophenyl)hex-3-ene 在温和条件下以良好的收率。显示成功取决于二氯甲烷溶剂中是否存在痕量水。
