WebFriedel-Crafts Alkylation. The purpose of the Friedel-Crafts alkylation reaction is to synthesize aromatic alkanes. This reaction occurs when an alkyl chloride reacts with an aromatic ring in the presence of a Lewis acid, like aluminum chloride (AlCl 3) or iron chloride (FeCl 3 ). Due to the formation of carbocations, rearrangements occur to ... WebThe synthetic processing included a Friedel-Crafts acylation, reduction, chloride shift, and Grignard relation. The products by each step had analysed using IR and 1H NMR spectroscopy and the final product was additionally confirmed by molten point analysis. ... the -tetrahy-droquinolines via a tandem allylic azide rearrangement/Friedel ... WebApr 13, 2024 · Since 1º-carbocations are prone to rearrangement, it is usually not possible to introduce 1º-alkyl substituents larger than ethyl by Friedel-Crafts alkylation. Solution C.
