Cover Feature: The Influence of Secondary Interactions on the [N−I−N]+ Halogen Bond (Chem. Eur. J. 55/2021)

A three‐center halogen bond modulates the reactivity of a halonium ion and is thereby applicable for controlling the halogenation of alkenes. Chelation, strain, steric hindrance, and electrostatic interactions influence the halonium release rate. Combined experimental and theoretical analysis of the...

Description
Summary:A three‐center halogen bond modulates the reactivity of a halonium ion and is thereby applicable for controlling the halogenation of alkenes. Chelation, strain, steric hindrance, and electrostatic interactions influence the halonium release rate. Combined experimental and theoretical analysis of the reaction mechanism highlights the impact of secondary interactions, and is expected to provide a handle on the induction of stereoselectivity in electrophilic halogenation.
