WebStep 2: Mechanism of Gattermann – Koch Reaction. When a Lewis acid (aluminium chloride) is introduced to the species, it quickly eliminates a chloride ion. The species … The Gattermann reaction, (also known as the Gattermann formylation and the Gattermann salicylaldehyde synthesis) is a chemical reaction in which aromatic compounds are formylated by a mixture of hydrogen cyanide (HCN) and hydrogen chloride (HCl) in the presence of a Lewis acid catalyst such as AlCl3. It is named for the German chemist Ludwig Gattermann and is similar to the Friedel–Crafts …

WebSandmeyer Reaction. The substitution of an aromatic amino group is possible via preparation of its diazonium salt and subsequent displacement with a nucleophile (Cl-, I-, CN-, RS-, HO-). Many Sandmeyer Reactions proceed under copper (I) catalysis, while the Sandmeyer-type reactions with thiols, water and potassium iodide don't require catalysis. WebStep 1. The first step of the Gattermann Koch reaction mechanism is the generation of the reactive species which can later be used to react on …
Web11.7.2 Background. The Sandmeyer reaction is a versatile synthetic tool by which an amino group on an aromatic ring is replaced with a wide range of substituents by converting an amino group attached to an aromatic ring into a diazonium salt that can be transformed into several functional groups. In this experiment, the 2-iodobenzoic acid is synthesized …
