Can Gatterman-Koch reaction be considered similar to Friedel-Crafts acylation? Discuss.


In Gatterman-Koch reaction, benzono or ite derivative is treated with CO and HCl in presence of anhydrous aluminum chloride to produce benzaldehyde.

                  

While in Friedel-Craft acylation, acyl group is transferred to carbon of benzene and acyl benzene is obtained as a result.

This can be done by reaction of benzene with acyl chloride in the presence of anhydrous AlCl3.

Formyl chloride is unstable in nature. So, it can be transferred by only Gattermann-Koch reaction not by Friedel-Craft reaction.
