Abstract
Halogen bonding has become a prominent tool in organocatalysis, offering versatile and efficient applications. This paper presents a metal-free method to catalyze electrophilic bromination reactions of electron-deficient arenes through zwitterionic dual halogen bond catalysis. We study the potential of an underexplored class of zwitterionic iodonium compounds as both halogen bond donors and acceptors. This method is particularly significant as it operates under mild conditions, which is beneficial for maintaining the integrity of sensitive substrates. Furthermore, density functional theory calculations were used to gain insights into the dual halogen bond activation mode underlying the catalytic process.
