Friedel Crafts

Friedel Crafts reactions occur in organic chemistry and there are two types including alkylation and acylation. Alkylation is the addition of an alkyl chain on a halogen. An example would be adding chlorine with two carbons to a benzene ring and resulting in a benzene ring with an ethyl off the ring. Limitations to be cautious of for these reactions include having no meta-deactivators on the benzene ring, no amino groups, no phenyl or vinyl alkyl halide, and possible rearrangement. If a reaction breaks one of the rules, then the reaction will not take place. On the other hand, there are Friedel Craft acylations such as adding a carbon double bonded to an oxygen and single bonded to a chlorine. The limitations for these reactions include having no meta-deactivators on the ring and no amino groups on the ring. Similarly to the alkylation limitations, if a limitation is violated then the acylation will not take place.
