Gattermann reaction: The gattermann reaction can be defined

The gattermann reaction can be defined as a method of formylation of aromatic ring compounds. The reaction is also known by the names of Gattermann salicylaldehyde synthesis as well as gattermann formylation. The gattermann reaction is similar to the Friedel-Crafts reaction. The Gattermann Koch reaction is defined as a mechanism that begins with the formation of the reactive species with the usage of an Acid. The main objective of the reaction is the attachment of a formyl group (-CHO group) to an aromatic system. Gattermann reaction ... 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 aluminium chloride (AlCl 3). [1] What is Gattermann Koch’s Reaction ? In the presence of anhydrous aluminium chloride and traces of copper (I) chloride, benzene reacts with carbon monoxide and hydrochloric acid to produce benzaldehyde. This reaction is known as Gattermann -Koch reaction . Here copper (I) chloride acts as a co-catalyst.
