The Gattermann-Koch reaction, is a reaction in which CO and hydrochloric acid are used to produce a benzaldehyde-derivative from a benzene-derivative in one step.Benzaldehyde and many aromatic aldehydes are conveniently synthesized by this reaction. Presence of traces of copper chloride are also needed.
