WebGabriel Phthalimide Synthesis: Gabriel Phthalimide Synthesis was discovered by a German chemist named Siegmund Gabriel. The Gabriel synthesis is a chemical reaction used to obtain primary amines from primary alkyl halides. Gattermann Reaction: The Gattermann Reaction is named after a German chemist, Ludwig Gattermann. 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.

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 … WebGattermann-Skita synthesis redirects to pyridine's main page but is located only in a very small section and doesn't have its own article name space.
