WebFriedel-Crafts Alkylation is a chemical reaction where the proton in the aromatic compound gets substituted with the alkyl group only. The reaction takes place in the presence of anhydrous aluminium chloride. Anhydrous aluminium chloride may also be replaced with any other Lewis acids such as Ferric chloride. WebFriedel-Crafts reaction is one of the most useful synthetic tools in organic chemistry, mainly in the synthesis of aromatic ketones. The active catalysts for this reaction are modified zeolites and are preferable catalysts when shape selectivity affects the formation of the expected product. In this review, our aim is to corroborate recent ...

WebThe first arylation strategy for the synthesis of enantioenriched propargylamines is disclosed. This approach, which is complementary to previous alkynylation and alkylation strategies, involves a C(sp2)−C(sp3) bond formation, and is based on the first asymmetric Friedel–Crafts‐type arylation reaction of C‐alkynyl imines. Asymmetric Friedel–Crafts … WebFriedel-Crafts Alkylation reaction involves the addition of an alkyl group to a benzene ring via electrophilic aromatic substitution and is the best method to prepare alkyl benzene. Step 1: In this reaction, anhydrous AlCl3 is used as it acts as a Lewis acid and removes the chloride ion from the substrates and results into a cation.
