The Hoffmann elimination is an organic reaction used to convert an amine with a B-hydrogen to an alkene using met hyl iodide, silver oxide and water under thermal conditions The mechanism begins with an attack of the amine on met hyl iodide to form an ammonium iodide salt. The iodide reacts with silver oxide to form silver iodide which is insoluble …
Hoffmann Bromamide Reaction Mechanism. Hoffmann bromamide reaction mechanism generally includes the use of an alkali as a strong base to attack the amide, leading to the deprotonation and the subsequent generation of an anion. This reaction is used for the conversion of a primary amide to a primary amine with one less carbon atom.
