Abstract

A halogen bond catalyzed bromo‐carbocyclization of N‐cinnamyl sulfonamides and O‐cinnamyl phenyl ethers has been developed. N‐methyl 4‐iodopyridinium triflate is used as the halogen‐bonding organocatalyst and the reaction is highly chemoselective. This report represents the first proof‐of‐concept for halogen‐bonding organocatalyst‐promoted electrophilic halogenation. Mechanistic study suggests the autocatalytic nature of this reaction.
