Alkylation is a chemical reaction that entails transfer of an alkyl group. The alkyl group may be transferred as an alkyl carbocation, a free radical, a carbanion, or a carbene (or their equivalents). Alkylating agents are reagents for effecting alkylation. Alkyl groups can also be removed in a process known as … See more Nucleophilic alkylating agents deliver the equivalent of an alkyl anion (carbanion). The formal "alkyl anion" attacks an electrophile, forming a new covalent bond between the alkyl group and the electrophile. The … See more Alkylation in biology causes DNA damage. It is the transfer of alkyl groups to the nitrogenous bases. It is caused by alkylating agents such as EMS (Ethyl Methyl Sulphonate). Bifunctional alkyl groups which have two alkyl groups in them cause cross … See more Several commodity chemicals are produced by alkylation. Included are several fundamental benzene-based feedstocks such as ethylbenzene (precursor to See more Complementing alkylation reactions are the reverse, dealkylations. Prevalent are ether dealkylations. See more C-alkylation C-alkylation is a process for the formation of carbon-carbon bonds. The largest example of this takes place in the alkylation units of petrochemical plants, which convert low-molecular-weight alkenes into … See more In a conventional oil refinery, isobutane is alkylated with low-molecular-weight alkenes (primarily a mixture of propene and butene) in the presence of a Brønsted acid catalyst, which can … See more • Hydrodealkylation • Transalkylation • Alkynylation • Friedel–Crafts reaction • Category:Alkylating agents See more WebNational Center for Biotechnology Information

22.7: Alkylation of Enolate Ions - Chemistry LibreTexts

WebAlkylation and dealkylation reactions are characteristics especially for poly[alkylalkylene (arylene) phosphate]s in which the alkyl radical in the side chain is methyl or ethyl (Scheme 2.32).In these reactions, the α-carbon atom of the side alkoxy group plays the role of the electrophilic center. Nucleophiles such as the amino group and chlorine anion prefer to … Webalkylation units are operated at 5–10 °C (40–50 F). Above 10 °C, oxidation and side reactions are promoted, and the deteriorate-alkylate yield and quality while acid consumption increases. It is impossible to run the reaction below 0 °C (32 F) because acid viscosity will be too high and agitation becomes difficult.Above 21 °C (70 F ...
