Selective and effective iodination of alkyl-substituted benzenes with elemental iodine activated by Selectfluor F-TEDA-BF4
Selective direct introduction of an iodine atom into alkyl-substituted benzene derivatives was effectively achieved by reaction of target molecules with elemental iodine in the presence of 1-chloromethyl-4-fluoro- 1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (Selectfluor F-TEDA-BF4). The number of iodine atoms introduced could be modulated by the molar ratio between substrate, iodine and F-TEDA-BF4.
