A mechanism for the reaction in which toluene reacts with CO and HCl in the presence of CuCl/AlCl 3 to yield p-methoxybenzaldehyde (an example of Gattermann-Koch reaction) is to be proposed. The Gattermann-Koch Reaction is not applicable to phenol and phenol ethers because they "could not be successfully formylated at atmospheric pressure in benzene as a solvent."
