Abstract:
Aryl halides are common synthetic targets themselves, and also highly versatile synthetic intermediates. Aryl chlorides are much more widely available and easier to synthesise than the other halide derivatives, so the development of effective methods for interconverting aryl halide derivatives would therefore be extremely useful. This article outlines which transformations are particularly desirable, and describes the progress that has been made on developing methods for carrying out those transformations using copper, nickel or palladium catalysts. The possible mechanisms of these reactions are discussed, with a view to identifying areas for future investigation.

Electrophilic Addition to Alkynes: Halogenation
Halogenation is another class of electrophilic addition reactions where a halogen molecule gets added across a π bond. In alkynes, the presence of two π bonds allows for the addition of two equivalents of halogens (bromine or chlorine). The addition of the first halogen molecule forms a trans-dihaloalkene as the major product and the cis isomer as the minor product. Subsequent addition of the second equivalent yields the tetrahalide.
Halogenation of Alkenes
Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
