Alkene Reactivity 2: Halonium Ions
Channel: Oxford College Chemistry Courses: Scharf
Date: 2023-05-18

The concerted reaction of alkenes with dihalogens to produce halonium ions is explained, as well as their fate in the presence of a nucleophile. This results in anti addition of a nucleophile and a halide across the double bond. The regiochemistry of halonium ion opening is also introduced (explained in a later video).
