Gattermann – Koch Reaction Mechanism - Vedantu
WebApplications and Industry Use. The Gattermann Koch reaction is used in industry to synthesize aldehydes of Alkylbenzene. This reaction could not be used to react with non-alkylbenzenes. There are two ways to carry out this reaction: At atmospheric pressure of CO with Cu 2 Cl 2 , ‘or’. At high pressure of CO without Cu 2 Cl 2. WebSep 11, 2024 · $\begingroup$ There isn't really any literature evidence to support the fact that it does react @ oxygen (though it is quite probable). In the Gattermann-Koch mechanism, the intermediate is highly reactive, the Gattermann modification avoids this, making it amenable to synthesis (Gattermann conditions + phenol are fine and have … togetherモード 設定
