Question

Yes, one can consider Gatterman-Koch reaction similar to Friedel Craft’s acylation reaction.

In Friedel Craft’s acylation reaction, an aryl group or benzene is treated with acid chloride in presence of anhydrous AlCl₃ and corresponding aldehyde or ketone is formed. In Gatterman-Koch reaction, benzene is treated with CO and HCl in presence of AlCl₃ and CuCl to yield benzaldehyde.

If the acid chloride in Friedel Craft’s acylation reaction is H-CO-Cl, then the product will be benzaldehyde.
