In organic chemistry, an aryl halide (also known as haloarene) is an aromatic compound in which one or more hydrogen atoms, directly bonded to an aromatic...

is reacted with an organic halide to form a new carbon-carbon bond, concomitant with loss of CO2. Aryl and alkyl halides participate. Metal catalyst...

phthalimide. Aryl halides are much less reactive toward amines and for that reason are more controllable. A popular way to prepare aryl amines is the...

a comparatively easy method to make aryl halides as the gaseous product can be separated easily from aryl halide. When an iodide is to be made, copper...

The Wurtz–Fittig reaction is the chemical reaction of an aryl halide, alkyl halides, and sodium metal to give substituted aromatic compounds. Following...

bonds via the palladium-catalyzed coupling reactions of amines with aryl halides. Although Pd-catalyzed C–N couplings were reported as early as 1983,...

reagent would attack the ester group over the aryl halide. For the coupling of aryl halides with aryl Grignard reagents, nickel chloride in tetrahydrofuran...

reagents can be used for the Suzuki coupling, e.g., aryl or vinyl boronic acids and aryl or vinyl halides. Work has also extended the scope of the reaction...

between a copper(I) acetylide and an aryl halide in pyridine, forming a disubstituted alkyne and a copper(I) halide. The reaction was described in 1963...

reaction is the copper-promoted conversion of aryl halides to aryl ethers, aryl thioethers, aryl nitriles, and aryl amines. These reactions are examples of...

alkyl halides, aryl halides and vinyl halides do not react. There are notable exceptions to this trend, including 1,2-dichloroethene and trityl halides. Some...

The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts using copper salts as reagents or catalysts. It...

aryl halide 1 accepts an electron from a radical initiator forming a radical anion 2. This intermediate collapses into an aryl radical 3 and a halide...

reaction that replaces an alkyl or aryl halide with a formyl group using a N,N-disubstituted formamide. For primary alkyl halides this produces the homologous...

to achieve high selectivity for cross product. For example, aryl halide and alkyl halide can be differentiated by the reactivity trends of two electrophiles...

exchange is frequently used to prepare vinyl-, aryl- and primary alkyllithium reagents. Vinyl halides usually undergo lithium–halogen exchange with retention...

Braun synthesis is an organic reaction in which an aryl halide reacts with cuprous cyanide to yield an aryl nitrile. The reaction was named after Karl Wilhelm...

Bromochlorobenzenes are mixed aryl halides (aryl chloride and aryl bromide) consisting bromine and chlorine as substituents on a benzene ring. All three...

can displace halide substituents on a carbon atom through the SN2 mechanism. With a catalyst, they also alkylate alkyl and aryl halides, as exemplified...
