WebExperiment 1: Friedel-Crafts Acylation Background: Goals: a) work with water-sensitive reagents; b) design experimental procedure and work-up; and c) to assess the procedural design. Electrophilic aromatic substitution reactions take place between the nucleophilic π electrons of an aromatic ring and a strong electrophile. WebFriedel–Crafts acylations of anthracene often lead to the formation of mixtures of the 1-, 2- and 9-isomers < B-64MI 306-01 >. The 1- and 2-isomeric ketones have been shown to …
Web14 Dec 2024 · The Friedel-Crafts acylation is the introduction of an acyl group to an aromatic compound by the mechanism of electrophilic aromatic substitution.
