Can Gatterman-Koch reaction be considered similar to Friedel Craft’s acylation? Discuss.


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.
