WebJan 5, 2010 · Pyrroles and furans also undergo the Gattermann aldehyde synthesis: with HCl and HCN, furan gives furfuraldehyde. The Houben–Hoesch ketone synthesis is also applicable to the preparation of acyl derivatives of furans and pyrroles, e.g., ethyl 2,4-dimethylpyrrole-3-carboxylate with MeCN and HCl yields ethyl 5-acetyl-2,4-dimethyl-3 …

WebIn 1915, K.Hoesch reported the extension of the Gattermann reaction for the synthesis of aromatic ketones using nitriles instead of hydrogen cyanide, and by replacing the aluminium chloride with the milder zinc chloride. Over ten years later, J. Houben demonstrated that this reaction principally worked for polyphenols or polyphenolic ethers. WebMar 14, 2024 · In 1897, L. Gattermann and J.A. Koch developed a formylation of toluene with CO and HCl as the acylating agent under Friedel-Crafts acylation conditions, 3 which is now well known as the Gattermann-Koch reaction (Scheme 1). ...
