Zinc is used effectively in the dehalogention of vicinal dihalides because a carbon zinc complex is formed in the mechanism which is probably more stable. This reaction is also known as Simmon' Smith reaction. The stability and usefulness of the Simmons-Smith reagent (zinc metal) may be attributed in part to the higher covalency of ...
In chemistry, dehydrohalogenation is an elimination reaction which removes a hydrogen halide from a substrate. The reaction is usually associated with the synthesis of alkenes, but it has wider applications. See more Traditionally, alkyl halides are substrates for dehydrohalogenations. The alkyl halide must be able to form an alkene, thus halides having no C–H bond on an adjacent carbon are not suitable substrates. Aryl … See more • Dehydrohalogenation of Alkyl Halides Archived 2024-04-11 at the Wayback Machine See more Epoxides Chlorohydrins, compounds with the connectivity R(HO)CH-CH(Cl)R', undergo dehydrochlorination … See more WebDehydrohalogenation is normally accomplished by reacting the alkyl halide with a strong base, such as sodium ethoxide.
