Gattermann koch reaction: Gattermann-Koch Reaction About Gattermann-Koch

Gattermann-Koch Reaction About Gattermann-Koch Reaction Benzaldehyde and many aromatic aldehydes are conveniently synthesized by treating benzene (or other aromatic compounds) with a mixture of carbon monoxide and hydrogen chloride (compounds of formyl chloride) in the presence of an equimolecular quantity of Lewis acid and a trace of copper (I) chloride. The initially formed cation (C+HO) adds to the benzene nucleus to give the σ complex which yields the aldehyde. Reaction Mechanism of ...
