Arylvinyl halides are a class of organic compounds characterized by the presence of a vinyl halide group attached to an aryl ring. The vinyl halide group consists of a carbon-carbon double bond where at least one of the carbon atoms is bonded to a halogen atom (such as chlorine, bromine, or iodine). The aryl ring is an aromatic hydrocarbon group, typically a benzene ring.

These compounds can be synthesized through various organic reactions. One common method involves the addition of hydrogen halides to arylalkynes. Another approach is the dehydrohalogenation of vicinal dihalides where one halogen is on a vinyl carbon and the other is on an adjacent carbon. Palladium-catalyzed cross-coupling reactions, such as the Suzuki or Heck reactions, can also be employed to form the carbon-carbon bond between the aryl and vinyl halide moieties.

Arylvinyl halides are significant intermediates in organic synthesis. The halogen atom on the vinyl group is susceptible to nucleophilic substitution and can be replaced by other functional groups. Furthermore, the carbon-carbon double bond can undergo various addition reactions, including hydrogenation, halogenation, and epoxidation. The aryl ring can also participate in electrophilic aromatic substitution reactions. Due to their versatile reactivity, arylvinyl halides are valuable building blocks for the synthesis of more complex molecules, including pharmaceuticals, agrochemicals, and materials. Their properties and applications are an active area of research in organic chemistry.
