4.10: Alkylation and Acylation of Aromatic Rings - The …

WebIn this video, we're going to an acylation, which is very similar to the alkylation. We start off with benzene, and to benzene we add an acyl chloride. And so this right here, you could think about as an acyl group. We're also going to use aluminum chloride once again as our catalyst, and you can see the acyl group has substituted in for one of ... Electrophilic aromatic substitution is an organic reaction in which an atom that is attached to an aromatic system (usually hydrogen) is replaced by an electrophile. Some of the most important electrophilic aromatic substitutions are aromatic nitration, aromatic halogenation, aromatic … Meer weergeven The most widely practised example of this reaction is the ethylation of benzene. Approximately 24,700,000 tons were produced in 1999. (After dehydrogenation and polymerization, the commodity plastic polystyrene is … Meer weergeven The overall reaction mechanism, denoted by the Hughes–Ingold mechanistic symbol SEAr, begins with the aromatic ring attacking … Meer weergeven Compared to benzene, the rate of electrophilic substitution on pyridine is much slower, due to the higher electronegativity of the nitrogen atom. Additionally, the nitrogen in pyridine easily gets a positive charge either by protonation (from Meer weergeven Compared to benzene, furans, thiophenes, and pyrroles are more susceptible to electrophilic attack. These compounds all contain an atom with an unshared pair of electrons ( Meer weergeven Both the regioselectivity—the diverse arene substitution patterns—and the speed of an electrophilic aromatic substitution are affected by the substituents already attached to the benzene ring. In terms of regioselectivity, some groups promote substitution … Meer weergeven The attachment of an entering group to a position in an aromatic compound already carrying a substituent group (other than hydrogen). The entering group may displace that … Meer weergeven Electrophilic aromatic substitutions with prochiral carbon electrophiles have been adapted for asymmetric synthesis by switching to Meer weergeven i got 5 on it slowed

Electrophilic aromatic substitution

WebNitration of Methyl Benzoate A Study of the Regiochemistry in Electrophilic Aromatic Substitution Introduction Nitration is one of the most important examples of electrophilic aromatic substitution.
