14.7: Aryl Halides - Chemistry LibreTexts
2021年7月31日 · The simple aryl halides generally are resistant to attack by nucleophiles in either SN1 S N 1 or SN2 S N 2 reactions (Table 14-6). However, this low reactivity can be changed dramatically by changes in the reaction conditions and the structure of the aryl halide.
Aryl halide - Wikipedia
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 ring are replaced by a halide. Haloarenes are different from haloalkanes because they exhibit many differences in methods of preparation and properties.

identify the conditions necessary for an aryl halide to undergo nucleophilic aromatic substitution, and give an example of such a reaction. write the detailed mechanism for a nucleophilic aromatic substitution reaction. compare the mechanism of a nucleophilic aromatic substitution reaction and the S N 1 and S N 2 mechanisms discussed earlier.
Aryl Halide: Definition, Structure, Examples, and Properties
Aryl halides are frequently utilized in cross-coupling reactions, which involve the formation of a new carbon-carbon bond between two different aryl or alkyl groups. Palladium -catalyzed reactions, such as the Suzuki-Miyaura and Heck reactions, are examples of cross-coupling reactions employing aryl halides.
Aryl Halide Reactions - Aryl Halides Nucleophilic Substitution
Aryl halides are aromatic compounds with hydrogen atoms. Learn the reactions of aryl halide nucleophilic substitution and its structure & properties @BYJU'S.
Aryl halides are halides in which the halogen is attached directly to an aromatic ring. Carbon-halogen bonds in aryl halides are shorter and stronger than carbon-halogen bonds in alkyl halides. Because the carbon-halogen bond is stronger, aryl halides react more slowly than alkyl halides when carbon-halogen bond breaking is rate determining.
