Friedel Crafts Alkylation of Benzene Reaction Mechanism - Tons of Examples!

TL;DR

This video explains the Friedel-Crafts alkylation reaction, its mechanism, limitations, and alternative methods for alkylating benzene.

Transcript

in this video we're going to go over the frito crafts alkylation reaction of benzene so here is the generic reaction so let's start with benzene and what we're going to do is we're going to react with an alkyl chloride using aluminum chloride as the catalyst and the net effect is that we're replacing a hydrogen atom with an alkyl group or with an r...
