WebThe mechanism of this reaction involves an acid bromide enol instead of the expected carboxylic acid enol. The reaction stats with the reaction of the carboxylic acid with PBr 3 to form the acid bromide and HBr. The HBr then catalyzes the formation of the acid bromide enol which subsequently reacts with Br 2 to give alpha bromination. WebZn/CH3CO₂H H₂/Pd NANH, NH3 1. Br2/PBr3 2. H₂O.
