Friedel-Crafts Acylation The Friedel-Crafts acylation reaction involves the addition of an acyl group to an aromatic ring. Typically, this is done by employing an acid chloride (R-(C=O)-Cl) and a Lewis acid catalyst such as AlCl3. In a Friedel-Crafts acylation reaction, the aromatic ring ...

What is the Difference Between Friedel-Crafts Alkylation and Friedel-Crafts Acylation? The fundamental difference between Friedel-Crafts alkylation and Friedel-Crafts acylation is that the former reaction alkylates an aromatic hydrocarbon, whereas the latter acylates the arene. Furthermore, Friedel-Craft...
Stork Enamine Alkylation refers to the process of alpha alkylation and acylation of ketones or aldehydes using enamine or imine formation, followed by the addition of an enamine to a Michael acceptor and subsequent hydrolysis to form alkylated aldehydes or ketones. ...
Fărcasiu and Schlosberg193 demonstrated that, in the presence of carbon monoxide, the t-alkyl cation generated in situ from the dealkylation of a tertiary alkyl arene resulted in acylation of the dealkylated arene, as shown in Scheme 15. Sign in to download full-size image Scheme 15. ...

Driven by intramolecular acylation, intermediate 33 releases carbene and delivers the final product 28. Meanwhile, Wu and coworkers [80] also documented similar results. The radical relay reaction is not limited to coupling to carbonyl at C1, but can also extend to coupling to carbonyl at C3....
this sequence may provide a practical access to enantiopure NOBIN library. Bearing this in mind, we initiated our investigation by exploring different catalytic strategies for the resolution of1a. These strategies included an NHC-catalyzed acylation of the phenolic OH group, which was done in our pr...
