Loss of a hydrogen halide to form a carbon–carbon multiple bond. Along a chlorinated polymer backbone, repeated elimination can create unsaturated or conjugated segments rather than exclusively changing ester side groups.
A concerted elimination in which a base removes a beta hydrogen as a leaving group departs and a pi bond forms. Orbital alignment and substrate structure affect the allowed pathway.
antiperiplanar conformation elimination in a cyclohexane chair with axial leaving group and axial beta hydrogen.
An elimination mechanism involving ionization to a carbocation before beta deprotonation forms the alkene. Its limiting unimolecular rate law assumes ionization controls the rate.
In an E1cb elimination, deprotonation first produces a conjugate-base intermediate, followed by leaving-group loss. Dehydration of an appropriate aldol product can form a conjugated enone.
