Electrophilic halogenation. In organic chemistry, an electrophilic aromatic halogenation is a type of electrophilic aromatic substitution. This organic reaction is typical of aromatic compounds and a very useful method for adding substituents to an aromatic system. A few types of aromatic compounds, such as phenol, will react without a catalyst ...
A halogen addition reaction is a simple organic reaction where a halogen molecule is added to the carbon–carbon double bond of an alkene functional group. [1] The general chemical formula of the halogen addition reaction is: C=C + X 2 → X−C−C−X. (X represents the halogens bromine or chlorine, and in this case, a solvent could be CH 2 ...
The nitration of benzene is achieved via the action of the nitronium ion as the electrophile. The sulfonation with fuming sulfuric acid gives benzenesulfonic acid. Aromatic halogenation with bromine, chlorine, or iodine gives the corresponding aryl halides. This reaction is typically catalyzed by the corresponding iron or aluminum trihalide.
In commercial applications, the alkylating agents are generally alkenes, some of the largest scale reactions practiced in industry.Such alkylations are of major industrial importance, e.g. for the production of ethylbenzene, the precursor to polystyrene, from benzene and ethylene and for the production of cumene from benzene and propene in cumene process:
Halogenation. In chemistry, halogenation is a chemical reaction which introduces one or more halogens into a chemical compound. Halide -containing compounds are pervasive, making this type of transformation important, e.g. in the production of polymers, drugs. [1] This kind of conversion is in fact so common that a comprehensive overview is ...
RXNO:0000021. The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts using copper salts as reagents or catalysts. [1][2][3][4] It is an example of a radical-nucleophilic aromatic substitution. The Sandmeyer reaction provides a method through which one can perform unique transformations on benzene ...
finkelstein-reaction. RSC ontology ID. RXNO:0000155. The Finkelstein reaction, named after the German chemist Hans Finkelstein, [1] is a type of S N 2 reaction (Substitution Nucleophilic Bimolecular reaction) that involves the exchange of one halogen atom for another. It is an equilibrium reaction, but the reaction can be driven to completion ...
The Wohl–Ziegler reaction[1][2] is a chemical reaction that involves the allylic or benzylic bromination of hydrocarbons using an N -bromosuccinimide and a radical initiator. [3] Best yields are achieved with N -bromosuccinimide in carbon tetrachloride solvent. Several reviews have been published. [4][5]
