Reaction equation: Mechanism of formation on the electrophile: Mechanism of Friedel-Crafts Alkylation
Step 1. Addition of the electrophile. Step 2. Deprotonation. Mechanism of Friedel-Crafts Alkylation
Primary and methyl cations are too unstable to be formed so
the Lewis acid-base complex is the effective electrophile. Friedel-Crafts Alkylation and Rearrangements
Rearrangements occur especially with primary alkyl
halides. The electrophile is formed by hydride migration to form a more
stable cation. Alternative Sources for Carbocat...
