Unformatted text preview: and the aluminum trichloride catalyst is regenerated along with a molecule of hydrochloric acid. A word of caution about this reaction: because the aluminum trichloride generates what can essentially be thought of as a carbocation, rearrangments can occur to produce a more highly-substituted carbocation. For example: Addition of 1-Chloro-2-Methylpropane to benzene with aluminum trichloride results in the rearranged product, t-butyl benzene, and not the product that you might initially expect (work out the mechanism if you cannot see how that product is attained). An example of a Friedel-Crafts alkylation:...
